1.     BASIS OF PRESENTATION AND ORGANIZATION

The accompanying unaudited condensed consolidated financial statements of Triumph Group, Inc. (the "Company") have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and six months ended September 30, 2018, are not necessarily indicative of results that may be expected for the year ending March 31, 2019. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the fiscal 2018 audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended March 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on May 22, 2018.

The Company designs, engineers, manufactures, repairs and overhauls a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. The Company serves a broad, worldwide spectrum of the aviation industry, including original equipment manufacturers of commercial, regional, business, and military aircraft and aircraft components, as well as commercial and regional airlines and air cargo carriers.

The Company has reclassified certain prior period amounts in order to conform to the current period presentation.

Standards Recently Implemented

Adoption of ASU 2014-09

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) that supersedes Accounting Standards Codification ("ASC") Topic 605 (“legacy GAAP”). Subsequently, the FASB issued several updates to ASU 2014-09, which are pending content or otherwise codified in ASC Topic 606 (“ASC 606”). ASU 2014-09 includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40 (“ASC 340-40”). The Company adopted ASC 606 using the modified retrospective method (“method”) effective as of April 1, 2018 (“date of initial application”). Under this method, the cumulative effect of the adoption of ASC 606 is recognized as an adjustment to retained earnings on the date of initial application (“Transition Adjustment”), and the comparative financial statements for prior periods are not adjusted and continue to be reported under legacy GAAP. The Transition Adjustment was a decrease to retained earnings of $584,900. Financial information for fiscal years 2019 and 2018 is presented under ASC 606 and under legacy GAAP, respectively. The tables below reflect adjusted fiscal year 2019 financial statement amounts as if the Company had been reporting under legacy GAAP for items that are materially different.

The adoption of ASC 606 does not impact the Company's cash flows or the underlying economics of the Company's contracts with customers. However, the pattern and timing of revenue and profit recognition, as well as financial statement presentation and disclosures, has changed.

The significant changes and the qualitative and quantitative impact of the adoption of ASC 606 are noted below:

a.Revenue from Contracts with Customers

Generally, the Company no longer uses the units-of-delivery method, and the historical use of contract blocks to define contracts for accounting purposes has been replaced by accounting contracts as identified under ASC 606. The Company's accounting contracts under ASC 606 are for the specific number of units for which orders have been received, which is typically for fewer units than what was used to define contract blocks under legacy GAAP. In most of the Company's contracts, the customer has options or requirements to purchase additional products and services that do not represent material rights since the options are at their standalone pricing.

The primary effect of the Company’s adoption of ASC 606 (outside of the Aerospace Structures segment) was to recognize revenue over time for certain of its contracts, which is a change from recognition based on shipping terms under the legacy GAAP accounting policy.

(unaudited)

b.Capitalized Preproduction Costs

Under legacy GAAP, certain capitalized preproduction costs were deferred over the life of the contract block; in certain situations this is not permitted under ASC 606. Accordingly, capitalized preproduction costs of $865,843 (pre-tax), net of previously recognized forward loss reserves of $343,983 (pre-tax), were eliminated, resulting in a decrease to retained earnings as of April 1, 2018.

c.Contract Assets and Contract Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract assets in the amount of $565,414 were established in the Transition Adjustment.

Contract liabilities primarily represent cash received that is in excess of revenues recognized and is contingent upon the satisfaction of performance obligations. Contract liabilities in the amount of $288,287 were established in the Transition Adjustment, which reflects consideration received prior to the date of initial application that previously represented customer advances and additional forward losses due to change in block sizes. This liability will be recognized as revenue earlier if the options are not fully exercised, or immediately if the contract is terminated prior to the options being fully exercised.

d.Contract Costs

The Company’s accounting for preproduction, tooling and certain other costs has not changed since these costs generally do not fall within the scope of ASC 340-40, however certain related assets have been reclassified from inventory to property and equipment as they are costs to fulfill obligations beyond 1 year. Incurred production costs for anticipated contracts (satisfaction of performance obligations, which have commenced because the Company expects the customer to exercise options) continue to be classified as inventory.

e.Practical Expedients

The Company has adopted ASC 606 only for contracts that were not substantially completed under legacy GAAP on the date of initial application. For these contracts, the Company has reflected the aggregate effect of all modifications executed prior to the date of initial application when identifying satisfied and unsatisfied performance obligations, for determining the transaction price and for allocating the transaction price.

The following tables summarize the impacts of adopting ASC 606 on the Company’s consolidated financial statements for the three and six months ended September 30, 2018.

Adoption of ASU 2017-07

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires an employer to report the service cost component of net periodic pension benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period, with other cost components presented separately from the service cost component and outside of income from operations. ASU 2017-07 also allows only the service cost component of net periodic pension benefit cost to be eligible for capitalization when applicable. ASU 2017-07 was effective for years beginning after December 15, 2017. The Company adopted this standard on April 1, 2018, applying the presentation requirements retrospectively. We elected to apply the practical expedient, which allows us to reclassify amounts disclosed previously in the employee benefit plans note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. Provisions related to presentation of the service cost component eligibility for capitalization were applied prospectively.

The effect of the retrospective presentation change related to the net periodic benefit cost of our defined benefit pension and postretirement plans on our condensed consolidated statements of operations was as follows:

	For the Three Months Ended
	As Previously Reported September 30, 2017		Impact of Adoption of ASU 2017-07			As Adjusted September 30, 2017
Cost of sales	$	579,864	$	18,539		$	598,403
Selling, general and administrative	74,581		861			75,442
Pension settlement charge	523		(523		)	—
Non-service defined benefit income	—		(18,877		)	(18,877		)
	For the Six Months Ended
	As Previously Reported September 30, 2017		Impact of Adoption of ASU 2017-07			As Adjusted September 30, 2017
Cost of sales	$	1,207,210	$	37,000		$	1,244,210
Selling, general and administrative	153,883		1,806			155,689
Pension settlement charge	523		(523		)	—
Non-service defined benefit income	—		(38,283		)	(38,283		)

During the first quarter of the fiscal year ended March 31, 2019, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to an inseparable change in estimate from a change in accounting principles. This charge is presented on the accompanying condensed consolidated statements of operations within "Cost of sales."

Adoption of ASU 2017-12

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which expands component and fair value hedging, specifies the presentation of the effects of hedging instruments, and eliminates the separate measurement and presentation of hedge ineffectiveness. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU 2017-12 as of April 1, 2018. The adoption of ASU 2017-12 did not have a material impact on the Company’s condensed consolidated financial statements.

Standards Issued Not Yet Implemented

In February 2018, the FASB issued ASU 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The guidance in ASU 2018-02 allows an entity to elect to reclassify the stranded tax effects related to the Tax Cuts and Jobs Act of 2017 (the “Act”) from accumulated other comprehensive income into retained earnings. ASU 2018-02 is effective for fiscal years

beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material effect on the Company’s condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). The guidance in ASU 2016-02 aims to increase transparency and comparability across organizations by requiring lease assets and lease liabilities to be recognized on the balance sheet as well as key information to be disclosed regarding lease arrangements. The amendments in ASU 2016-02 are effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU 2018-11, Leases: Targeted Improvements. Among other things, this ASU provides entities with a transition option to recognize the cumulative-effect adjustment from the modified retrospective application to the opening balance of retained earnings in the period of adoption rather than the earliest period presented in the financial statements. We currently expect to adopt ASU 2016-02, as updated, effective April 1, 2019. The Company has not yet selected a transition method. The adoption of this new accounting standard will result in an increase in the recognition of right-of-use assets and lease liabilities. However, the Company is continuing to evaluate the impact of adopting this new accounting guidance and, therefore, cannot reasonably estimate the impact on the results of operations or cash flows at this time.

2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The Company makes estimates of the cost of satisfying the performance obligations in its contracts that may extend over many years. Cost estimates reflect currently available information and the impact of any changes to cost estimates, based upon the facts and circumstances, are recorded in the period in which they become known.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. The Company’s contracts with customers are typically for products and services to be provided at fixed stated prices but may also include variable consideration. Variable consideration may include, but is not limited to, unpriced contract modifications; cost sharing provisions; incentives and awards; non-warranty claims and assertions; provisions for non-conformance and rights to return; or other payments to, or receipts from, customers. The Company estimates the variable consideration using the expected value or the most likely amount based upon the facts and circumstances, available data and trends, and the history of resolving variability with specific customers.

The Company regularly commences work and incorporates customer-directed changes prior to negotiating pricing terms for engineering work, product modifications, and other statements of work. The Company's contractual terms typically provide for price negotiations after certain customer-directed changes have been accepted by the Company. Prices are estimated and related costs are deferred until they are contractually agreed upon with the customer. When a contract is modified, the Company evaluates whether additional distinct products and services have been promised and whether allocation of consideration is necessary. If not, the modification is treated as a change to the performance obligations within the existing contract, or otherwise accounted for as a new contract prospectively.

The Company allocates the consideration for a contract to the performance obligations on the basis of their relative standalone selling price. The Company estimates the likelihood of the amount of options that the customer is going to exercise when assessing the existence of performance obligations with respect to this allocation or for assessing the impact of loss contracts. The Company typically provides warranties on all of the Company's products and services. Warranties are typically not priced separately and customers cannot purchase them independently of the products or services under contract; therefore, warranties do not create performance obligations. Triumph's warranties generally provide assurance to the Company's customers that the products or services meet the specifications in the contract. In the event that there is a warranty claim because of a covered material or workmanship issue, the Company may be required to pay the customer for repairs or to perform the repair. Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These costs are accrued at the time of the sale and are recorded as cost of sales. These estimates are established using historical information on the nature, frequency, and the cost experience of warranty

claims. In the case of new development products or new customers, the Company also considers other factors such as the type and nature of the new product or new customer, among others; these considerations involve the use of management judgment. Actual results could differ from those estimates and assumptions.

For the three months ended September 30, 2018, cumulative catch-up adjustments from changes in estimates, including changes in forward loss estimates, increased net sales, operating loss, net loss, and loss per share by approximately $3,459, $(10,191), $(10,191) and $(0.21), net of tax, respectively. For the three months ended September 30, 2017, cumulative catch-up adjustments from changes in estimates decreased operating loss, net loss and loss per share by approximately $8,416, $6,733 and $0.14, net of tax, respectively.

For the six months ended September 30, 2018, cumulative catch-up adjustments from changes in estimates, including changes in forward loss estimates, decreased net sales and increased operating loss, net loss and loss per share by approximately $(3,292), $(12,968), $(12,968) and $(0.26), net of tax, respectively. In addition, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to a change in estimate from a change in accounting principles, which is presented on the accompanying condensed consolidated statements of operations within "Cost of sales." For the six months ended September 30, 2017, cumulative catch-up adjustments from changes in estimates decreased operating loss, net loss and loss per share by approximately $7,916, $6,333 and $0.13, net of tax, respectively.

Revenue Recognition

A significant majority of the Company’s revenues are from long-term supply agreements with various aerospace manufacturers. The Company participates in its customers’ programs by providing design, development, manufacturing, and support services across its various segments. During the early stages of a program, this frequently involves non-recurring design and development services, including tooling. As the program matures, the Company provides recurring manufacturing of products in accordance with customer design and schedule requirements. Many contracts include clauses that provide sole supplier status to the Company for the duration of the program’s life. The Company's long-term supply agreements typically include fixed price volume-based terms and require the satisfaction of performance obligations for the duration of the program’s life.

The identification of an accounting contract with a customer and the related promises requires an assessment of each party’s rights and obligations regarding the products or services to be transferred, including an evaluation of termination clauses and presently enforceable rights and obligations. In general, these long-term supply agreements are legally governed by Master Supply Agreements (or General Terms & Agreement) under which special business provisions (or work package agreements) define specific program requirements. Purchase orders (or authorizations to proceed) are issued under these agreements to reflect presently enforceable rights and obligations for the units of products and services being purchased. The units for accounting purposes (“accounting contract”) are typically determined by the purchase orders. Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. A single program may result in multiple contracts for accounting purposes, and within the respective contracts, non-recurring work elements and recurring work elements may result in multiple performance obligations. The Company generally contracts directly with its customers and is the principal in all current contracts.

Management considers a number of factors when determining the existence of a contract and the related performance obligations that include, but are not limited to: the nature and substance of the business exchange; the contractual terms and conditions; the promised products and services; the termination provisions in the contract; the presently enforceable rights and obligations of the parties to the contract; the nature and execution of the customer’s ordering process and how the Company is authorized to perform work; whether the promised products and services are capable of being distinct and are distinct within the context of the contract; as well as how and when products and services are transferred to the customer.

Revenue is recognized when, or as, control of promised products or services transfers to a customer and is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those products or services. Revenue is recognized over time as work progresses when the Company is entitled to the reimbursement of costs plus a reasonable profit for work performed for which the Company has no alternate use or when performing work on a customer-owned asset. For these performance obligations that are satisfied over time, the Company generally recognizes revenue using an input method with revenue amounts being recognized proportionately as costs are incurred relative to the total expected costs to satisfy the performance obligation. The Company believes that costs incurred as a portion of total estimated costs is an appropriate

(dollars in thousands, except per share data)

(unaudited)

measure of progress toward satisfaction of the performance obligation since this measure reasonably depicts the progress of the work effort.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer (which is generally based on shipping terms). For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Shipping and handling costs are not considered performance obligations and are included in cost of sales as incurred.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. A subset of the Company’s current contracts include significant financing components because the timing of the transfer of the underlying products and services under contract are at the customers’ discretion. The Company's contracts with customers generally require payment under normal commercial terms after delivery. Payment terms are typically within 30 to 120 days of delivery. The total transaction price is allocated to each of the identified performance obligations using the relative standalone selling price to reflect the amount the Company expects to be entitled for transferring the promised products and services to the customer. A majority of the Company’s agreements with customers include options for future purchases. As allowed by ASC 606, for all of its contracts the Company has elected to exclude sales and other similar taxes from the transaction price since the Company generally is not subject to collecting sales tax. As a result, the Company's collections from customers for these taxes are on a net basis.

Standalone selling price is the price at which the Company would sell a promised good or service separately to a customer. Standalone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When standalone selling prices for the Company’s products and services are generally not observable, the Company uses either the “Expected Cost plus a Margin” or "Adjusted Market Assessment" approaches to determine standalone selling price. Expected costs are typically derived from the available periodic forecast information. If a contract modification changes the overall transaction price of an existing contract, the Company allocates the new transaction price on the basis of the relative standalone selling prices of the performance obligations, and cumulative adjustments, if any, are recorded in the current period.

The Company also identifies and estimates variable consideration for contractual provisions such as unpriced contract modifications, cost sharing provisions, and other receipts or payments to customers. The timing of satisfaction of performance obligations and actual receipt of payment from a customer may differ and affects the balances of the contract assets and liabilities.

For contracts that are deemed to be loss contracts, the Company establishes forward loss reserves for total estimated costs that are in excess of total estimated consideration in the period in which they become known. The Company records forward loss reserves for all performance obligations in the aggregate for the accounting contract.

Included in net sales of Integrated Systems and Aerospace Structures is the non-cash amortization of acquired contract liabilities that were recognized as fair value adjustments through purchase accounting from various acquisitions. For the three months ended September 30, 2018 and 2017, the Company recognized $16,804 and $27,898 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations. For the six months ended September 30, 2018 and 2017, the Company recognized $34,038 and $57,371 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations.

Disaggregation of Revenue

The Company disaggregates revenue based on the method of measuring satisfaction of the performance obligation either over time or at a point in time. Additionally, the Company disaggregates revenue based upon the end market where products and services are transferred to the customer. The Company’s principal operating segments and related revenue are noted in Note 13, Segments.

Concentration of Credit Risk

The Company’s trade accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from Boeing (representing commercial, military and space) represented approximately 15% and 10% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Gulfstream represented approximately 7% and 16% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Bombardier represented approximately 12% and 1% as of September 30, 2018 and March 31, 2018, respectively. The Company had no other concentrations of credit risk of more than 10%.

Sales to Boeing for the six months ended September 30, 2018, were $527,896, or 31% of net sales, of which $110,971, $410,133, and $6,792 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Boeing for the six months ended September 30, 2017, were $507,330, or 33% of net sales, of which $105,304, $397,817 and $4,209 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

Sales to Gulfstream for the six months ended September 30, 2018, were $174,805, or 10% of net sales, of which $1,065, $173,437, and $303 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Gulfstream for the six months ended September 30, 2017, were $198,525, or 13% of net sales, of which $654, $197,674, and $197 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries.

Stock-Based Compensation

The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for the three months ended September 30, 2018 and 2017, was $3,266 and $3,459, respectively. Stock-based compensation expense for the six months ended September 30, 2018 and 2017, was $5,728 and $3,418, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to employees. Upon the exercise of stock options or vesting of restricted stock, the Company first transfers treasury stock, then issues new shares.

Intangible Assets

The components of intangible assets, net, are as follows:

Amortization expense for the three months ended September 30, 2018 and 2017, was $13,203 and $14,550, respectively. Amortization expense for the six months ended September 30, 2018 and 2017, was $26,436 and $29,375, respectively.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its divestitures (see Note 3).

Warranty Reserves

A reserve has been established to provide for the estimated future cost of warranties on our delivered products. The Company periodically reviews the reserves and adjustments are made accordingly. A provision for warranty on products delivered is made on the basis of historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The majority of the Company's agreements include a three-year warranty, although certain programs have warranties up to twenty years. The warranty reserves as of September 30, 2018 and March 31, 2018, were $65,158 and $69,588, respectively.

Supplemental Cash Flow Information

The Company received income tax refunds, net of payments of $7,120 and paid $5,133 for income taxes, net of refunds, for the six months ended September 30, 2018 and 2017, respectively.

The Company made interest payments of $38,587 and $31,507 for the six months ended September 30, 2018 and 2017, respectively.

During the six months ended September 30, 2018 and 2017, the Company financed $372 and $1,153, respectively, of property and equipment additions through capital leases.

As of September 30, 2018, the Company remains able to purchase an additional 2,277,789 shares under the existing stock repurchase program. However, there are certain restrictions placed on the repurchase program by the Company's lenders that prevent any repurchases at this time.

3.     DIVESTED OPERATIONS AND ASSETS HELD FOR SALE

In July 2018 and August 2018, respectively, the Company sold all of the shares of Triumph Structures - East Texas, Inc. as well as all of the shares of Triumph Structures - Los Angeles, Inc., and Triumph Processing, Inc. (collectively, the "fiscal 2019 divestitures") for combined cash proceeds of $40,000 and a note receivable of $7,000. The note receivable was collected subsequent to September 30, 2018. As a result of these sales, the Company recognized losses of $17,202 which are presented on the accompanying condensed consolidated statements of operations within "Loss on divestitures." The operating results for the fiscal 2019 divestitures are included in Aerospace Structures through the date of divestiture.

In March 2018, the Company sold all of the shares of Triumph Structures - Long Island, LLC ("TS-LI") for cash proceeds of $9,500 and a note receivable of $1,400. The note receivable was collected subsequent to September 30, 2018. As a result of the sale of TS-LI, the Company recognized a loss of $10,370. The operating results of TS-LI were included in Aerospace Structures through the date of divestiture.

In September 2017, the Company sold all of the shares of Triumph Processing - Embee Division, Inc. ("Embee") for total cash proceeds of $64,986. As a result of the sale of Embee, the Company recognized a loss of $17,857. The operating results of Embee were included in Integrated Systems through the date of divestiture.

In December 2016, the Company entered into a definitive agreement to divest the assets and business of Triumph Air Repair, the Auxiliary Power Unit Overhaul Operations of Triumph Aviation Services - Asia, Ltd. and Triumph Engines - Tempe ("Engines and APU") for total cash proceeds of $60,364. As a result, the Company recognized a loss of $14,263 on the sale. The operating results of Engines and APU were included in Product Support through the date of divestiture. The transaction closed during the quarter ended June 30, 2017. An option to purchase the repair part line of Triumph Aviation Services - Asia, Ltd. was executed by the buyer of Engines and APU in May 2018 for total cash proceeds of $17,794. This transaction is expected to close during the second half of fiscal 2019 and is expected to result in a gain. The related assets and liabilities are shown as held for sale on the accompanying condensed consolidated balance sheets.

The divestitures of these entities does not represent a strategic shift and is not expected to have a major effect on the Company's operations or financial results, as defined by ASC 205-20, Discontinued Operations; as a result, the divestitures do not meet the criteria to be classified as discontinued operations.

To measure the amount of impairment related to the divestitures, the Company compared the fair values of assets and liabilities at the evaluation dates with the carrying amounts at the end of the month prior to the respective evaluation dates. The assets and liabilities of the above divestitures and assets held for sale are categorized as Level 2 within the fair value hierarchy. The key assumption included the negotiated sales price of the assets and the assumptions of the liabilities (see Note 2 above for the definition of levels).

4.    CONTRACT ASSETS AND CONTRACT LIABILITIES

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. No impairments to contract assets were recorded for the period ended September 30, 2018.

Contract liabilities are established for cash received that is in excess of revenues recognized and are contingent upon the satisfaction of performance obligations. Contract liabilities primarily consist of cash received on contracts for which revenue has been deferred since the Company has not fulfilled its obligation to the customer, along with provisions for forward losses due to changes in block size and performance obligations.

	September 30, 2018			March 31, 2018			Change
Contract assets	$	569,934		$	37,573		$	532,361
Contract liabilities	(354,963		)	(321,191		)	(33,772		)
Net contract asset	$	214,971		$	(283,618	)	$	498,589

The increase in contract assets reflects the effect of the adoption of ASC 606 of approximately $565,000, partially offset by revenue recognized during the period from performance obligations satisfied in previous periods of $3,292 and the net impact of additional unbilled revenues recorded in excess of revenue recognized during the period. The increase in contract liabilities reflects the effect of the adoption of ASC 606 of approximately $288,000 and the net impact of additional deferred revenues recorded in excess of revenue recognized during the period. For the period ended September 30, 2018, the Company recognized $87,394 of revenue that was included in the contract liability balance at the beginning of the period.

5.    PERFORMANCE OBLIGATIONS

As of September 30, 2018, the Company has the following unsatisfied, or partially unsatisfied, performance obligations that are expected to be recognized in the future as noted in the table below. The Company expects options to be exercised in addition to the amounts presented below.

	Total		Less than 1 year		1-3 years		4-5 years		More than 5 years
Unsatisfied performance obligations	$	4,997,125	$	2,563,022	$	1,543,950	$	328,552	$	561,601

Total inventories	$	533,583	$	1,427,169

At March 31, 2018, work-in-process inventory previously included capitalized preproduction costs on newer development programs. Capitalized preproduction costs include non-recurring engineering, planning and design, including applicable overhead, incurred before production is manufactured on a regular basis. Significant customer-directed work changes can also cause preproduction costs to be incurred. These costs are typically recovered over a contractually determined number of ship set deliveries.

Following the adoption of ASU 2014-09, the capitalized preproduction costs and forward loss provisions associated with these programs were recognized in the transition adjustment. At March 31, 2018, the balance of development program inventory, composed principally of capitalized preproduction costs, excluding progress payments related to the Company's contracts with Bombardier for the Global 7500 program ("Bombardier") and Embraer for the second generation E-Jet program ("Embraer") was as follows:

	March 31, 2018
	Inventory		Capitalized Preproduction		Forward Loss Provision			Total Inventory, net
Bombardier	$	321,780	$	685,503	$	(343,000	)	$	664,283
Embraer	38,125		180,340		(983		)	217,482
Total	$	359,905	$	865,843	$	(343,983	)	$	881,765

During the fiscal year ended March 31, 2016, the Company recorded a $399,758 forward loss charge for the Bombardier Global 7500 wing program ("Global 7500"). Under our contract for the Bombardier Global 7500, the Company has the right to design, develop and manufacture wing components for the Global 7500 program. The Global 7500 contract provides for fixed pricing and requires the Company to fund certain up-front development expenses, with certain milestone payments made by Bombardier.

The Global 7500 program charge resulted in the impairment of previously capitalized preproduction costs due to the combination of cost recovery uncertainty, higher than anticipated non-recurring costs and increased forecasted costs on recurring production. The increases in costs were driven by several factors, including changing technical requirements, increased spending on the design and engineering phase of the program, and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers.

The Global 7500 program has continued to incur costs since March 2016 in support of the development and transition to production.

In May 2017, Triumph Aerostructures and Bombardier entered into a comprehensive settlement agreement that resolved all outstanding commercial disputes between them, including all pending litigation, related to the design, manufacture and supply of wing components for the Global 7500 business aircraft. The settlement reset the commercial relationship between the companies and allowed each company to better achieve its business objectives going forward.

Further cost increases or an inability to meet revised recurring cost forecasts on the Global 7500 program may result in additional forward loss reserves in future periods, while improvements in future costs compared with current estimates may result in favorable adjustments if forward loss reserves are no longer required.

The Company is still in the early production stages for the Bombardier and Embraer programs, as these aircrafts are scheduled to enter service in fiscal 2019. Transition of these programs from development to recurring production levels is dependent upon the success of the programs achieving flight testing and certification, as well as the ability of the Bombardier and Embraer programs to generate acceptable levels of aircraft sales. The failure to achieve these milestones and level of sales or significant cost overruns may result in additional forward losses.

Revolving Credit Facility

In July 2018, the Company, its subsidiary co-borrowers and guarantors entered into a Tenth Amendment to the Credit Agreement (the “Tenth Amendment” and the existing Credit Agreement as amended by the Tenth Amendment, the "Credit Agreement") and with the Administrative Agent and the Lenders party thereto. Among other things, the Tenth Amendment modifies certain financial covenants and other terms and lowers the capacity upon completion of certain asset sales and will automatically reduce to $700,000 at March 31, 2019. The Tenth Amendment also adds an additional mandatory prepayment provision requiring that the Company prepay the outstanding revolving credit loans as set forth in the Tenth Amendment. The recent divestitures resulted in a reduction of the capacity under the Credit Agreement from $800,000 to $750,000 during the three months ended September 30, 2018.

In connection with the Tenth Amendment to the Credit Agreement, the Company incurred $1,694 of financing costs. These costs, along with the $8,961 of unamortized financing costs subsequent to the Ninth Amendment, are being amortized over the remaining term of the Credit Agreement. In accordance with the reduction in the capacity of the Credit Agreement, the Company wrote off a proportional amount of unamortized financing fees existing prior to the Tenth Amendment.

In July 2017, the Company entered into a Ninth Amendment to the Credit Agreement (the “Ninth Amendment” and the existing Credit Agreement, as amended by the Ninth Amendment, the “Credit Agreement”) with the Administrative Agent and the Lenders party thereto to, among other things: (i) permit the Company to incur High Yield Indebtedness (as defined in the Credit Agreement) in an aggregate principal amount of up to $500,000, subject to the Company’s obligations to apply the net proceeds from an offering to repay the outstanding principal amount of the term loans in full; (ii) limit the mandatory prepayment provisions to eliminate the requirement that net proceeds received from the incurrence of Permitted Indebtedness (as defined in the Credit Agreement), including the High Yield Indebtedness, be applied to reduce the revolving credit commitments once the revolving credit commitments have been reduced to $800,000; (iii) amend certain covenants and other terms; and (iv) modify the current interest rate and letter of credit pricing tiers.

In May 2017, the Company entered into an Eighth Amendment to the Credit Agreement, among the Company and its lenders to, among other things: (i) eliminate the total leverage ratio financial covenant; (ii) increase the maximum permitted senior secured leverage ratio financial covenant applicable to each fiscal quarter, commencing with the fiscal quarter ended March 31, 2017, and to revise the step-downs applicable to such financial covenant; (iii) reduce the aggregate principal amount

of commitments under the revolving line of credit to $850,000 from $1,000,000; (iv) modify the maturity date of the term loans so that all of the term loans will mature on March 31, 2019; and (v) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions.

The obligations under the Credit Agreement and related documents are secured by liens on substantially all assets of the Company and its domestic subsidiaries pursuant to a Second Amended and Restated Guarantee and Collateral Agreement, dated as of November 19, 2013, among the administrative agent, the Company and the subsidiaries of the Company party thereto.

Pursuant to the Credit Agreement, the Company can borrow, repay and re-borrow revolving credit loans, and cause to be issued letters of credit, in an aggregate principal amount not to exceed $750,000 outstanding at any time. The Credit Agreement bears interest at either: (i) London Interbank Offered Rate (LIBOR) plus between 1.50% and 3.50%; (ii) the prime rate; or (iii) an overnight rate at the option of the Company. The applicable interest rate is based upon the Company’s ratio of total indebtedness to earnings before interest, taxes, depreciation and amortization. In addition, the Company is required to pay a commitment fee of 0.50% on the unused portion of the Credit Agreement. The Company’s obligations under the Credit Agreement are guaranteed by the Company’s domestic subsidiaries.

At September 30, 2018, there were $332,661 in borrowings and $31,156 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. At March 31, 2018, there were $112,887 in borrowings and $30,641 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. The level of unused borrowing capacity under the Revolving Line of Credit provisions of the Credit Agreement varies from time to time depending in part upon its compliance with financial and other covenants set forth in the related agreement. The Credit Agreement contains certain affirmative and negative covenants, including limitations on specified levels of indebtedness to earnings before interest, taxes, depreciation and amortization, and interest coverage requirements, and includes limitations on, among other things, liens, mergers, consolidations, sales of assets, and incurrence of debt. If an event of default were to occur under the Credit Agreement, the lenders would be entitled to declare all amounts borrowed under it immediately due and payable. The occurrence of an event of default under the Credit Agreement could also cause the acceleration of obligations under certain other agreements. The Company is currently in compliance with all such covenants. Although the Company does not anticipate any violations of the financial covenants, its ability to comply with these covenants is dependent upon achieving earnings and cash flow projections. As of September 30, 2018, the Company had borrowing capacity under this agreement of $386,183 after reductions for borrowings, letters of credit outstanding under the facility and consideration of covenant limitations.

The Credit Agreement also provided for a variable rate term loan (the "2013 Term Loan"). The Company repaid the outstanding principal amount of the 2013 Term Loan in quarterly installments, on the first business day of each January, April, July and October. During August 2017, the 2013 Term Loan was paid in full with the proceeds from the Senior Notes due 2025.

The Company previously maintained an interest rate swap agreement to reduce its exposure to interest on the variable rate portion of its long-term debt. In conjunction with the repayment of the 2013 Term Loan, the Company terminated the interest rate swap receiving $280 upon settlement.

Receivables Securitization Facility

In November 2017, the Company amended the Securitization Facility decreasing the purchase limit from $225,000 to $125,000 and extending the term through November 2020. In connection with the Securitization Facility, the Company sells on a revolving basis certain trade accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. As of September 30, 2018, the maximum amount available under the Securitization Facility was $125,000. Interest rates are based on LIBOR plus a program fee and a commitment fee. The program fee is 0.13% on the amount outstanding under the Securitization Facility. Additionally, the commitment fee is 0.50% on 100.00% of the maximum amount available under the Securitization Facility. The Company secures its trade accounts receivable, which are generally non-interest bearing, in transactions that are accounted for as borrowings pursuant to the Transfers and Servicing topic of the ASC 860.

Interest on the 2025 Notes accrues at the rate of 7.750% per annum and is payable semiannually in cash in arrears on February 15 and August 15 of each year, commencing on February 15, 2018.

Financial Instruments Not Recorded at Fair Value

The carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximate fair value because of their short maturities (Level 1 inputs). Carrying amounts and the related estimated fair values of the Company’s financial instruments not recorded at fair value in the condensed consolidated financial statements are as follows:

	September 30, 2018				March 31, 2018
	Carrying Value		Fair Value		Carrying Value		Fair Value
Long-term debt	$	1,628,039	$	1,596,710	$	1,438,284	$	1,446,151

The fair value of the long-term debt was calculated based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements (Level 2 inputs), unless quoted market prices were available.

9.    INCOME TAXES

The Company follows the Income Taxes topic of ASC 740, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (the “Act”). The Act introduced tax reform that reduced the current corporate federal income tax rate from 35% to 21%, among other changes. The Act makes broad and complex changes to the U.S. tax code, and it will take time to fully evaluate the impact of these changes on the Company. The Company has prepared a reasonable estimate around the impact of the Act and has recorded a provisional impact (as described in the SEC's Staff Accounting Bulletin 118) to the tax provision in the period ended March 31, 2018. While the Company has computed and recorded these provisional amounts, these will be finalized within the established measurement period (not to exceed one year) as additional data and information is gathered. The Company determined that the amounts recorded are provisional as adjustments may occur due to additional guidance from the Internal Revenue Service and as certain tax positions are finalized when the Company files its fiscal 2018 tax returns. As of September 30, 2018, the Company has not made material revisions to the provisional tax impact of the Act. Any revisions will be included as an adjustment to the tax expense in the period in which the amounts are determined.

The Company is still evaluating the effects of the Act’s global intangible low-taxed income (“GILTI”) provisions and has not adopted an accounting policy on whether the Company will account for GILTI as a period expense or record deferred taxes on temporary basis differences expected to reverse as GILTI in future years. The Company's accounting for the effects of the GILTI provision is incomplete; however, the Company has included estimated GILTI tax related to current year operations in the Company's annualized effective tax rate and has not provided additional GILTI on deferred items.

The Act also introduces base erosion and anti-abuse tax provisions (“BEAT”) for companies that meet certain thresholds by effectively excluding deductions on certain payments to foreign related entities. Although the Company's analysis of the tax effects of the BEAT provision is incomplete, the Company does not expect to be subject to the tax.

The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of income tax expense. As of September 30, 2018 and March 31, 2018, the total amount of accrued income tax-related interest and penalties was $356 and $327, respectively.

As of September 30, 2018 and March 31, 2018, the total amount of unrecognized tax benefits was $17,374 and $11,532, respectively, most of which would impact the effective rate, if recognized. The Company does not anticipate that total unrecognized tax benefits will be reduced in the next 12 months.

As of September 30, 2018, the Company has a valuation allowance against principally all of its net deferred tax assets given insufficient positive evidence to support the realization of the Company’s deferred tax assets.  The Company intends to continue maintaining a valuation allowance on its deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances.  A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the release is recorded.  However, the exact timing and amount of the reduction in its valuation allowance is unknown at this time and will be subject to the earnings level the Company achieves during fiscal 2019 as well as the Company's income in future periods.

The effective income tax rate for the three months ended September 30, 2018, was (2.2)% as compared with 17.6% for the three months ended September 30, 2017. For the three months ended September 30, 2018, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

The effective income tax rate for the six months ended September 30, 2018, was (1.6)% as compared with 20.0% for the six months ended September 30, 2017. For the six months ended September 30, 2018, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

With few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations for fiscal years ended before March 31, 2014, or foreign income tax examinations by tax authorities for fiscal years ended before March 31, 2011.

As of September 30, 2018, the Company is subject to examination in one state jurisdiction and one foreign jurisdiction. The Company has filed appeals in a prior state examination related to fiscal years ended March 31, 1999 through March 31, 2005. Because of net operating losses acquired as part of the acquisition of Vought, the Company is subject to U.S. federal income tax examinations and various state jurisdictions for the years ended December 31, 2001 and after, related to previously filed Vought tax returns. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years.

10.    GOODWILL

The following is a summary of the changes in the carrying value of goodwill by reportable segment, from March 31, 2018 through September 30, 2018:

	Integrated Systems			Product Support			Total
Balance, March 31, 2018	$	523,893		$	68,935		$	592,828
Effect of exchange rate changes	(6,291		)	(19		)	(6,310		)
Balance, September 30, 2018	$	517,602		$	68,916		$	586,518

As of March 31, 2018 and September 30, 2018, Aerospace Structures had goodwill of $1,275,134, which was fully impaired.

11.     PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

The Company sponsors several defined benefit pension plans covering some of its employees. Certain employee groups are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans based upon their service to the Company or years of service accrued under the defined benefit pension plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company’s policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under U.S. government regulations, by making payments into a separate trust.

In addition to the defined benefit pension plans, the Company provides certain healthcare and life insurance benefits for eligible retired employees. Such benefits are unfunded. Employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age and years of service requirements. Election to participate for some employees must be made at the date of retirement. Qualifying dependents at the date of retirement are also eligible for medical coverage. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. From time to time, changes have been made to the benefits provided to various groups of plan participants. Premiums charged to most retirees for medical coverage prior to age 65 are based on years of service and are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans and a Medicare carve-out.

In accordance with the Compensation – Retirement Benefits topic of ASC 715, the Company has recognized the funded status of the benefit obligation as of the date of the last re-measurement, on the accompanying condensed consolidated balance sheets. The funded status is measured as the difference between the fair value of the plan’s assets and the pension benefit obligation or accumulated postretirement benefit obligation, of the plan. In order to recognize the funded status, the Company determined the fair value of the plan assets. The majority of the plan assets are publicly traded investments, which were valued based on the market price as of the date of re-measurement. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on our evaluation of data from fund managers and comparable market data.

13.     SEGMENTS

The Company has three reportable segments: Integrated Systems, Aerospace Structures and Product Support. The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate performance of its segments and allocate resources.

Integrated Systems consists of the Company’s operations that provide integrated solutions, including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs.  Capabilities include hydraulic, mechanical and electromechanical actuation, power and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units and Full Authority Digital Electronic Control fuel systems; hydro-mechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options.

Aerospace Structures consists of the Company’s operations that supply commercial, business, regional and military manufacturers with large metallic and composite structures. Products include wings, wing boxes, fuselage panels, horizontal and vertical tails and sub-assemblies such as floor grids. Aerospace Structures also has the capability to engineer detailed structural designs in metal and composites. It also includes the Company’s operations that produce close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities. Capabilities include complex machining; gear manufacturing; sheet metal fabrication; forming; advanced composite and interior structures; joining processes such as welding, autoclave bonding and conventional mechanical fasteners; and a variety of special processes, including super plastic titanium forming, aluminum and titanium chemical milling, and surface treatments. As described in Note 1, during the first quarter of the fiscal year ended March 31, 2019, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to an inseparable change in estimate from a change in accounting principles. This charge is included in Aerospace Structures operating income and is excluded from Segment Adjusted EBITDAP.

Product Support consists of the Company’s operations that provide full life cycle solutions for commercial, regional and military aircraft. The Company’s extensive product and service offerings include full post-delivery value chain services that simplify the MRO supply chain. Through its line maintenance, component MRO and postproduction supply chain activities, Product Support is positioned to provide integrated planeside repair solutions globally. Capabilities include fuel tank repair, metallic and composite aircraft structures, nacelles, thrust reversers, interiors, auxiliary power units and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories.

Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments, including loss on divestitures of $17,837 for the six months ended September 30, 2018.

The Company does not accumulate net sales information by product or service or groups of similar products and services and, therefore, the Company does not disclose net sales by product or service because to do so would be impracticable. Selected financial information for each reportable segment is as follows:

15.    COMMITMENTS AND CONTINGENCIES

In the ordinary course of business, the Company is involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations.

16.    RESTRUCTURING COSTS

During the fiscal years ended March 31, 2017 and 2016, the Company committed to restructuring plans involving certain of its businesses, as well as the consolidation of certain of its facilities. These plans are nearing completion, and as a result, the Company will have reduced its footprint by approximately 4.3 million square feet, will have reduced head count by approximately 2,500 employees and will have amended certain contracts. The Company originally estimated that it would record aggregate pre-tax charges of $195,000 to $210,000 related to these programs, which represent employee termination benefits, contract termination costs, accelerated depreciation, and facility closure and other exit costs. These charges have resulted in cash outlays and will continue to do so until the completion of the related programs. As of September 30, 2018, the Company has updated its estimate of the expected aggregate pre-tax charge to $204,400 upon completion of the restructuring and is considering whether additional programs, which could impact the estimated aggregate pre-tax charge estimate, may further support the achievement of the overall strategic objective of the restructuring plans. From the initiation of the plans through the six months ended September 30, 2018, the Company has incurred approximately $193,000, and expects to incur approximately $11,400 of additional pre-tax charges primarily from remaining employee termination benefits and facility consolidations.

The following table provides a summary of the Company's current aggregate cost estimates by major type of expense associated with the restructuring plans noted above:

Type of expense:	Total estimated amount expected to be incurred
Termination benefits	$	39,000
Facility closure and other exit costs (1)	32,200
Contract termination costs	20,700
Accelerated depreciation charges (2)	36,200
Other (3)	76,300
	$	204,400

(1) Includes costs to transfer product lines among facilities and outplacement and employee relocation costs.

(2) Accelerated depreciation charges are recorded as part of depreciation and amortization on the consolidated statements of operations.

(3) Consists of other costs directly related to the plan, including project management, legal, regulatory costs and other transformation related costs, such as costs to amend certain contracts.

The restructuring charges recognized for the three and six months ended September 30, 2018 and 2017, by type and by segment consisted of the following:

Management's Discussion and Analysis of

Financial Condition and Results of Operations

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

(The following discussion should be read in conjunction with the condensed consolidated financial statements contained elsewhere herein.)

OVERVIEW

We are a major supplier to the aerospace industry and have three operating segments: (i) Integrated Systems, whose companies’ revenues are derived from integrated solutions, including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs; (ii) Aerospace Structures, whose companies supply commercial, business, regional and military manufacturers with large metallic and composite structures and produce close-tolerance parts primarily to customer designs and model based definition, including a wide range of aluminum, hard metal and composite structure capabilities; and (iii) Product Support, whose companies provide full life cycle solutions for commercial, regional and military aircraft.

In July 2018 and August 2018, respectively, the Company sold all of the shares of Triumph Structures - East Texas, Inc. as well as all of the shares of Triumph Structures - Los Angeles, Inc., and Triumph Processing, Inc. (collectively, the "fiscal 2019 divestitures") for combined cash proceeds of $40.0 million and a note receivable of $7.0 million. As a result of these sales, the Company recognized losses of $17.2 million, which is presented on the accompanying condensed consolidated statements of operations within "Loss on divestitures." The operating results for the fiscal 2019 divestitures are included in Aerospace Structures through the date of divestiture.

Highlights for the second quarter of the fiscal year ending March 31, 2019, included:

• Net sales for the second quarter of the fiscal year ending March 31, 2019, were $855.1 million, compared with $745.2 million for the prior year period.

• Operating loss in the second quarter of fiscal 2019 was $2.0 million, compared with operating loss of $29.0 thousand for the second quarter of fiscal 2018.

• Net loss for the second quarter of fiscal 2019 was $14.7 million, compared with a net loss of $5.4 million for the second quarter of fiscal 2018.

• Backlog as of September 30, 2018, was $4.34 billion. Of our existing backlog of $4.34 billion, we estimate that approximately $1.63 billion will not be shipped by September 30, 2019.

• Net loss for the second quarter of fiscal 2019 was $0.30 per diluted common share, as compared with a net loss of $0.11 per diluted share in the prior year period.

• We used$197.2 million of cash flow from operating activities for the six months ended September 30, 2018, as compared with cash used in operations of $299.1 million in the comparable prior year period.

We committed to several plans that incorporate the restructuring of certain of our businesses as well as the consolidation of certain of our facilities. We expect to reduce our footprint by approximately 4.3 million square feet and to reduce head count by 2,500 employees. Over the course of the plans (which were initiated in fiscal 2016), we estimate that we will record aggregate pre-tax charges of $195.0 million to $210.0 million related to these plans, which represent employee termination benefits, contract termination costs, accelerated depreciation, and facility closure and other exit costs and will result in future cash outlays. For the six months ended September 30, 2018 and 2017, we recorded pre-tax charges of $15.9 million and $29.8 million, respectively, related to these plans.

Our restructuring plans and related activities were anticipated to generate annualized savings of approximately $300 million per year on a consolidated basis by fiscal year 2019 from facility consolidations, headcount reductions, operational efficiencies, and supply chain optimization. These anticipated savings were expected to come from our reportable segments approximately as follows: Integrated Systems - 23%; Aerospace Structures - 72% and Product Support - 5%. A significant portion of the anticipated savings are expected to be reinvested in business development, research and development, and capital improvements to help drive organic growth or to support previously negotiated contractual price step-downs. The Company remains on target for its consolidated anticipated savings goals; however, the nature of those savings has shifted over time to be

37

(continued)

more weighted toward our supply chain optimization and operational efficiencies than previously anticipated, offset by reduced expectations associated with the facility consolidations and headcount reductions.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (the “Act”). The Act introduced tax reform that reduced the current corporate federal income tax rate from 35% to 21%, among other changes. The Act makes broad and complex changes to the U.S. tax code and it will take time to fully evaluate the impact of these changes on the Company. The Company has prepared a reasonable estimate around the impact of the Act and has recorded a provisional impact (as described in Staff Accounting Bulletin 118) to the tax provision in the period ended March 31, 2018. While the Company has computed and recorded these provisional amounts, these will be finalized within the established measurement period (not to exceed one year) as additional data and information is gathered. The Company determined that the amounts recorded are provisional as adjustments may occur due to additional guidance from the Internal Revenue Service and as certain tax positions are finalized when the Company files its fiscal 2018 tax returns. As of September 30, 2018, the Company has not made revisions to the provisional tax impact of the Act. Any revisions will be included as an adjustment to the tax expense in the period in which the amounts are determined.

The Company is still evaluating the effects of the GILTI provisions; an accounting policy on whether the Company will account for GILTI as a period expense or record deferred taxes for anticipated GILTI has not been made. The Company's accounting for the effects of the GILTI provision is incomplete; however, the Company has included estimated GILTI tax related to current year operations in the Company's annualized effective tax rate and has not provided additional GILTI on deferred items.

The Act also introduces base erosion and anti-abuse tax provisions (“BEAT”) for companies that meet certain thresholds by effectively excluding deductions on certain payments to foreign related entities. Although the Company's analysis of the tax effects of the BEAT provision is incomplete, the Company does not expect to be subject to the tax.

The Company is still in the early production stages for the Bombardier and Embraer programs, as these aircrafts are scheduled to enter service in fiscal 2019. Transition of these programs from development to recurring production levels is dependent upon the success of the programs achieving flight testing and certification, as well as the ability of the Bombardier and Embraer programs to generate acceptable levels of aircraft sales. The failure to achieve these milestones and level of sales or significant cost overruns may result in additional forward losses.

In May 2017, Triumph Aerostructures and Bombardier entered into a comprehensive settlement agreement that resolved all then-outstanding commercial disputes between them, including all pending litigation, related to the design, manufacture and supply of wing components for Bombardier’s Global 7000/8000 business aircraft. The settlement reset the commercial relationship between the companies and allowed each company to better achieve its business objectives going forward. The Company and Bombardier continue to have programmatic and commercial discussions on the wing scope of work and are jointly analyzing the most cost-efficient supply chain arrangement to ensure continuity of supply and the long-term success of the program and both companies.

 Under our contract with Embraer, we have the exclusive right to design, develop and manufacture the center fuselage section III, rear fuselage section and various tail section components (rudder and elevator) for the E2-Jets. The contract provides for funding on a fixed amount of non-recurring costs, which will be paid over a specified number of production units. Higher than expected spending on the E2-Jets program has resulted in a near breakeven estimated profit margin percentage, with additional potential future cost pressures as well as opportunities for improved performance. Risks related to additional engineering as well as the recurring cost profile remain as this program completes flight testing.

We seek additional consideration for customer work statement changes throughout our contract life as a standard course of business.  We recently reached an agreement with Gulfstream across many programs we support including, but not limited to, the G650 wing program. We are also currently engaged with other customers in similar negotiations.  The ability to recover or negotiate additional consideration is not certain and varies by contract.  Varying market conditions for these products may also impact future profitability.

During April 2018, the Company reached an agreement with Gulfstream to optimize the supply chain on the Company's G650 work scope. The G650 wing box and wing completion work, which are now co-produced across three facilities at both companies, are planned for consolidation into Gulfstream's structures center of excellence in Savannah, Georgia. The Company will maintain its role as the supply chain integrator on the program.

In September 2017, the Company reached an agreement with Boeing to supply the wing, vertical tail and horizontal tail structures for the new T-X pilot training program for the U.S. Air Force. In September 2018, the U.S. Air Force awarded the contract to Boeing.

Although none of these new programs individually is expected to have a material impact on our net revenues, they do have the potential, either individually or in the aggregate, to materially and negatively impact our consolidated results of operations if future changes in estimates result in the need for a forward loss provision. Absent any such loss provisions, we do not anticipate that any of these new programs will significantly dilute our future consolidated margins.

In September 2017, the Company sold all of the shares of Triumph Processing - Embee Division, Inc. ("Embee") for total cash proceeds of $65.0 million. As a result of the sale of Embee, the Company recognized a loss of $17.9 million, which is included in Corporate. The operating results of Embee were included in Integrated Systems through the date of divestiture.

In March 2018, the Company sold all of the shares of Triumph Structures Long Island, LLC ("TS-LI") for cash proceeds of $9.5 million, and a note receivable of $1.4 million. As a result of the sale of TS-LI, the Company recognized a loss of $10.4 million which is presented on the accompanying condensed consolidated statements of operations as "Loss on divestitures." The operating results of TS-LI were included in Aerospace Structures through the date of divestiture.

In December 2016, the Company entered into a definitive agreement to divest Triumph Air Repair, the Auxiliary Power Unit Overhaul Operations of Triumph Aviation Services - Asia, Ltd. and Triumph Engines - Tempe ("Engines and APU"). As a result, the Company recognized a loss of $14.3 million on the sale. The operating results of Engines and APU were included in Product Support through the date of divestiture. The transaction closed during the quarter ended June 30, 2017. An option to purchase the repair part line of Triumph Aviation Services - Asia, Ltd. was executed by the buyer of Engines and APU in May 2018 for total cash proceeds of $17.8 million. This transaction is expected to close during the second half of fiscal 2019 and is expected to result in a gain. The related assets and liabilities are shown as held for sale on the accompanying condensed consolidated balance sheets.

RESULTS OF OPERATIONS

The following includes a discussion of our consolidated and business segment results of operations. The Company's diverse structure and customer base do not allow for precise comparisons of the impact of price and volume changes to our results. However, we have disclosed the significant variances between the respective periods.

Non-GAAP Financial Measures

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with U.S. GAAP. In accordance with Securities and Exchange Commission (the "SEC") guidance on Compliance and Disclosure Interpretations, we also disclose and discuss certain non-GAAP financial measures in our public filings and earning releases. Currently, the non-GAAP financial measures that we disclose are Adjusted EBITDA, which is our income from continuing operations before interest, income taxes, amortization of acquired contract liabilities, legal settlements, depreciation and amortization; and Adjusted EBITDAP, which is Adjusted EBITDA, before pension. We disclose Adjusted EBITDA on a consolidated and Adjusted EBITDAP on a consolidated and a reportable segment basis in our earnings releases, investor conference calls and filings with the SEC. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors more meaningfully evaluate and compare our future results of operations with our previously reported results of operations.

We view Adjusted EBITDA and Adjusted EBITDAP as operating performance measures and, as such, we believe that the U.S. GAAP financial measure most directly comparable to it is net income. In calculating Adjusted EBITDA and Adjusted EBITDAP, we exclude from net income (loss) the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. Adjusted EBITDA and Adjusted EBITDAP are not measurements of financial performance under U.S. GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss), income from continuing operations, or as an indicator of any other measure of performance derived in accordance with U.S. GAAP. Investors and potential investors in our securities should not rely on Adjusted EBITDA or Adjusted EBITDAP as a substitute for any U.S. GAAP financial measure, including net income (loss) or income from continuing operations. In addition, we urge investors and potential

39

Management's Discussion and Analysis of

Financial Condition and Results of Operations

(continued)

investors in our securities to carefully review the reconciliation of Adjusted EBITDA and Adjusted EBITDAP to net income (loss) set forth below, in our earnings releases and in other filings with the SEC and to carefully review the U.S. GAAP financial information included as part of our Quarterly Reports on Form 10-Q and our Annual Reports on Form 10-K that are filed with the SEC, as well as our quarterly earnings releases, and compare the U.S. GAAP financial information with our Adjusted EBITDA and Adjusted EBITDAP.

Adjusted EBITDA and Adjusted EBITDAP are used by management to internally measure our operating and management performance and by investors as a supplemental financial measure to evaluate the performance of our business that, when viewed with our U.S. GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our business. We have spent more than 20 years expanding our product and service capabilities, partially through acquisitions of complementary businesses. Due to the expansion of our operations, which included acquisitions, our income from continuing operations has included significant charges for depreciation and amortization. Adjusted EBITDA and Adjusted EBITDAP exclude these charges and provides meaningful information about the operating performance of our business, apart from charges for depreciation and amortization. We believe the disclosure of Adjusted EBITDA and Adjusted EBITDAP helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe Adjusted EBITDA and Adjusted EBITDAP are measures of our ongoing operating performance because the isolation of non-cash charges, such as depreciation and amortization, and non-operating items, such as interest, income taxes, pension and other postretirement benefits, provides additional information about our cost structure and, over time, helps track our operating progress. In addition, investors, securities analysts and others have regularly relied on Adjusted EBITDA and Adjusted EBITDAP to provide financial measures by which to compare our operating performance against that of other companies in our industry.

Set forth below are descriptions of the financial items that have been excluded from our net income to calculate Adjusted EBITDA and Adjusted EBITDAP and the material limitations associated with using these non-GAAP financial measures as compared to net income (loss) or income from continuing operations:

• Divestitures may be useful for investors to consider because they reflect gains or losses from sale of operating units. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

• Legal settlements may be useful for investors to consider because it reflects gains or losses from disputes with third parties. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

• Non-service defined benefit income from our pension and other postretirement benefit plans (inclusive of the adoption of ASU 2017-07) may be useful for investors to consider because they represent the cost of post retirement benefits to plan participants, net of the assumption of returns on the plan's assets and are not indicative of the cash paid for such benefits. We do not believe these earnings (expenses) necessarily reflect the current and ongoing cash earnings related to our operations.

• Amortization of acquired contract liabilities may be useful for investors to consider because it represents the non-cash earnings on the fair value of off-market contracts acquired through acquisitions. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

• Amortization expense (including intangible asset impairments) may be useful for investors to consider because it represents the estimated attrition of our acquired customer base and the diminishing value of product rights and licenses. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

• Depreciation may be useful for investors to consider because it generally represents the wear and tear on our property and equipment used in our operations. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.

• The amount of interest expense and other we incur may be useful for investors to consider and may result in current cash inflows or outflows. However, we do not consider the amount of interest expense and other to be a representative component of the day-to-day operating performance of our business.

• Income tax expense may be useful for investors to consider because it generally represents the taxes which may be payable for the period and the change in deferred income taxes during the period and may reduce the amount of funds otherwise available for use in our business. However, we do not consider the amount of income tax expense to be a representative component of the day-to-day operating performance of our business.

Management's Discussion and Analysis of

Financial Condition and Results of Operations

(continued)

Management compensates for the above-described limitations of using non-GAAP measures only to supplement our U.S. GAAP results and to provide additional information that is useful to gain an understanding of the factors and trends affecting our business.

The following table shows our Adjusted EBITDA and Adjusted EBITDAP reconciled to our net income (loss) for the indicated periods (in thousands):

Net sales increased by $110.0 million, or 14.8%, to $855.1 million for the three months ended September 30, 2018, from $745.2 million for the three months ended September 30, 2017. Organic sales adjusted for inter-segment sales increased $144.3 million, or 20.8%, partially offset by declines from divestitures of $34.3 million. Organic sales increased increased primarily due to shipments for narrow body programs such as the 737 and A320, military platforms aftermarket repairs for the KC-10 and C-17 and, the ramp on development programs. Net sales for the three months ended September 30, 2018, included $4.9 million in total non-recurring revenues, as compared with $1.7 million in non-recurring revenues for the three months ended September 30, 2017.

Cost of sales increased$126.1 million, or 21.1%, to $724.5 million for the three months ended September 30, 2018, from $598.4 million for the three months ended September 30, 2017. Organic cost of sales increased $158.8 million, or 29.0%. Organic cost of sales increases were partially offset by decreases from divestitures of $32.7 million. Organic cost of sales increased due to the increase in organic sales mentioned above, changes in sales mix, and additional forward loss provisions, primarily from the Bombardier Global 7500 program of $19.9 million that was partially offset by a reduction in the forward loss reserve on a Gulfstream program of $7.6 million. The organic gross margin for the three months ended September 30, 2018 was 15.3%, as compared with 19.7%, for the three months ended September 30, 2017.

Gross margin included net unfavorable cumulative catch-up adjustments on long-term contracts of $10.2 million. The cumulative catch-up adjustments to gross margin included gross favorable adjustments of $55.6 million and gross unfavorable adjustments of $65.8 million. Gross margin for the three months ended September 30, 2017, included net favorable cumulative catch-up adjustments of $8.4 million.

Segment operating income decreased by $15.2 million, or 34.7%, to an operating loss of $28.6 million for the three months ended September 30, 2018, from operating income of $43.8 million for the three months ended September 30, 2017. Organic segment operating income decreased $19.4 million or 39.1%. Organic operating income decreases were partially offset by increases from divestitures of $4.2 million. Organic operating income for the three months ended September 30, 2018 decreased due to the decreased gross margins.

Corporate expenses were $30.6 million for the three months ended September 30, 2018, as compared with $43.9 million for the three months ended September 30, 2017. The decrease in corporate expenses of $13.2 million, or 30.1%, included lower workers' compensation expenses of $5.9 million. Losses on divestitures for the three months ended September 30, 2018 and 2017, were $13.1 million and $20.4 million, respectively.

Interest expense and other increased by $3.3 million, or 13.2%, to $28.7 million for the three months ended September 30, 2018, compared with $25.4 million for the three months ended September 30, 2017, due to higher interest rates and relative debt levels offset by the favorable net change in foreign exchange rate changes of approximately $1.0 million compared with the prior year period.

The effective income tax rate for the three months ended September 30, 2018, was (2.2)% compared with 17.6% for the three months ended September 30, 2017. For the three months ended September 30, 2018, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

For the fiscal year ending March 31, 2019, the Company expects tax expense to be approximately $3 to $4 million with opportunity to be reduced further through the release of the valuation allowance that is discussed further in Note 9.

Business Segment Performance - Three months ended September 30, 2018 compared with three months ended September 30, 2017

We report our financial performance based on the following three reportable segments: Integrated Systems, Aerospace Structures and Product Support. The results of operations among our operating segments vary due to differences in competitors, customers, extent of proprietary deliverables and performance. For example, Integrated Systems, which generally includes proprietary products and/or arrangements in which we become the primary source or one of a few primary sources to our customers, whereby our unique manufacturing capabilities command a higher margin. Also, OEMs are increasingly focusing on assembly activities while outsourcing more manufacturing and repair to third parties, and as a result, are less of a competitive force than in previous years. This compares to Aerospace Structures, which generally includes long-term sole-source or preferred supplier contracts and the success of these programs provides a strong foundation for our business and positions us well for future growth on new programs and new derivatives. In contrast, Product Support provides MRO services on components and accessories manufactured by third parties, with more diverse competition, including airlines, OEMs and other third-party service providers. In addition, variability in the timing and extent of customer requests performed in Product Support can provide for greater volatility and less predictability in revenue and earnings than that experienced in Integrated Systems and Aerospace Structures segments.

Integrated Systems consists of the Company’s operations that provide integrated solutions, including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs.  Capabilities include hydraulic, mechanical and electromechanical actuation, power and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units and Full Authority Digital Electronic Control fuel systems; hydro-mechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options.

Aerospace Structures consists of the Company’s operations that supply commercial, business, regional and military manufacturers with large metallic and composite structures. Products include wings, wing boxes, fuselage panels, horizontal and vertical tails and sub-assemblies such as floor grids. Aerospace Structures also has the capability to engineer detailed structural designs in metal and composites. It also includes the Company’s operations that produce close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities. Capabilities include complex machining; gear manufacturing; sheet metal fabrication; forming; advanced composite and interior structures; joining processes such as welding, autoclave bonding and conventional mechanical fasteners; and a variety of special processes, including super plastic titanium forming, aluminum and titanium chemical milling, and surface treatments.

Product Support consists of the Company’s operations that provide full life cycle solutions for commercial, regional and military aircraft. The Company’s extensive product and service offerings include full post-delivery value chain services that simplify the MRO supply chain. Through its line maintenance, component MRO and postproduction supply chain activities, Product Support is positioned to provide integrated planeside repair solutions globally. Capabilities include fuel tank repair, metallic and composite aircraft structures, nacelles, thrust reversers, interiors, auxiliary power units and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories.

Management's Discussion and Analysis of

Financial Condition and Results of Operations

(continued)

Integrated Systems: Integrated Systems net sales increased by $29.9 million, or 6.3%, to $501.8 million for the six months ended September 30, 2018, from $471.9 million for the six months ended September 30, 2017. Organic sales increased $47.9 million, or 10.6%. The Embee divestiture contributed $18.1 million to the net sales for the six months ended September 30, 2017. Organic sales increased primarily due to rate increases on key commercial programs.

Integrated Systems cost of sales increased by $47.4 million, or 15.4%, to $354.9 million for the six months ended September 30, 2018, from $307.5 million for the six months ended September 30, 2017. Organic cost of sales increased $60.5 million, or 20.6%. The Embee divestiture contributed $13.2 million to the cost of sales for the six months ended September 30, 2017. The organic cost of sales increased due to the net sales increase noted above and due to sales mix. The organic gross margin for the six months ended September 30, 2018, was 29.3% compared with 35.1% for the six months ended September 30, 2017. The decrease in gross margin for the six months ended September 30, 2018, is the result of sales mix, higher cost associated with operational improvements and a settlement of customer assertions in the comparable prior period.

Integrated Systems operating income decreased by $13.3 million, or 15.1%, to $75.3 million for the six months ended September 30, 2018, from $88.6 million for the six months ended September 30, 2017. Organic operating income decreased $13.1 million, or 14.9%. The Embee divestiture contributed $0.2 million to the operating income for the six months ended September 30, 2017. Operating income decreased for the six months ended September 30, 2018, due to the decreased gross margin as noted above. The decrease in Adjusted EBITDAP year over year is due to the same factors that decreased operating income.

Integrated Systems operating income as a percentage of segment sales decreased to 15.0% for the six months ended September 30, 2018, as compared with 18.8% for the six months ended September 30, 2017, due to the decreased gross margin as noted above. These same factors noted above affecting the Adjusted EBITDAP contributed to the decreased Adjusted EBITDAP margin year over year.

Aerospace Structures: Aerospace Structures net sales increased by $129.7 million, or 13.9%, to $1.06 billion for the six months ended September 30, 2018, from $931.1 million for the six months ended September 30, 2017. Organic sales increased $164.8 million, or 19.6%. Net sales decreased as a result of the TS-LI and fiscal 2019 divestitures by $35.1 million. The organic sales increased due to the initial ramp up of production and deliveries on the Bombardier Global 7500 program and the favorable settlement on open assertions with other customers, partially offset by a decrease in revenue recognized from the amortization of acquired contract liabilities of $24.3 million. Net sales for the six months ended September 30, 2018, included $44.3 million in total non-recurring revenues, as compared with $2.5 million in total non-recurring revenues for the six months ended September 30, 2017.

Aerospace Structures cost of sales increased by $200.5 million, or 23.7%, to $1.05 billion for the six months ended September 30, 2018, from $847.0 million for the six months ended September 30, 2017. The organic cost of sales increased $238.7 million, or 31.5%. Cost of sales decreased as a result of the TS-LI and fiscal 2019 divestitures by $38.1 million. The cost of sales increased due to the increase in organic sales mentioned above and due to additional forward loss provisions from the adoption of ASU 2017-07 of $87.2 million as well as from the Bombardier Global 7500 program of $19.9 million that was partially offset by a reduction in the forward loss reserve on a Gulfstream program of $7.6 million. The organic gross margin for the six months ended September 30, 2018, was 1.1% compared with 10.1% for the six months ended September 30, 2017.

Aerospace Structures cost of sales for the six months ended September 30, 2018, included net unfavorable cumulative catch-up adjustments of $12.8 million. The cumulative catch-up adjustments to gross margin for the six months ended September 30, 2018, included gross favorable adjustments of $34.0 million and gross unfavorable adjustments of $46.8 million. Additionally, the adoption of ASU 2017-07 resulted in a change in estimates due to a change in accounting principles of $87.2 million. Segment cost of sales for the six months ended September 30, 2017, included net unfavorable cumulative catch-up adjustments of $7.9 million.

Aerospace Structures operating loss increased by $70.8 million, or 224.1%, to $102.3 million for the six months ended September 30, 2018, compared with an operating loss of $31.6 million for the six months ended September 30, 2017. The organic operating loss increased $80.5 million or 413.1%. Operating income increased as a result of the TS-LI and fiscal 2019 divestitures by $9.8 million. Organic operating loss increased for the six months ended September 30, 2018, due to the decreased gross margin noted above. The increase in Adjusted EBITDAP year over year is primarily due to improvement in operating performance and margins and changes in sales mix.

Aerospace Structures operating loss as a percentage of segment sales increased to 9.6% for the six months ended September 30, 2018, as compared with 3.4% for the six months ended September 30, 2017, due to the increase in operating loss

as noted above. These same factors as noted above for the Adjusted EBITDAP contributed to the increased Adjusted EBITDAP margin year over year.

Product Support: Product Support net sales increased by $3.6 million, or 2.7%, to $138.4 million for the six months ended September 30, 2018, from $134.8 million for the six months ended September 30, 2017. Organic sales increased $11.5 million, or 9.1%, due to increased demand in structural component repairs. The divestiture of Engines and APU contributed $7.9 million to net sales for the six months ended September 30, 2017.

Product Support cost of sales increased by $4.6 million, or 4.5%, to $105.2 million for the six months ended September 30, 2018, from $100.6 million for the six months ended September 30, 2017. Organic cost of sales increased $11.1 million, or 11.7%. Organic cost of sales increased due to increased volumes. The divestiture of Engines and APU contributed $6.5 million in cost of sales to the six months ended September 30, 2017. Organic gross margin for the six months ended September 30, 2018, was 24.0% compared with 25.8% for the six months ended September 30, 2017, and was impacted by learning curves on new programs.

Product Support operating income decreased by $0.5 million, or 2.5%, to $19.2 million for the six months ended September 30, 2018, from $19.7 million for the six months ended September 30, 2017. Organic operating income increased $0.5 million, or 3.1%, due to the increased organic sales noted above. The divestiture of Engines and APU contributed $1.1 million operating income for the six months ended September 30, 2017. The decreased gross margins contributed to the decrease in Adjusted EBITDAP year over year.

Product Support operating income as a percentage of segment sales decreased to 13.9% for the six months ended September 30, 2018, as compared with 14.6% for the six months ended September 30, 2017, due to the decreased gross profit noted above. These same factors contributed to the decreased Adjusted EBITDAP margin year over year.

Liquidity and Capital Resources

Our working capital needs are generally funded through cash flows from operations and borrowings under our credit arrangements. During the six months ended September 30, 2018, we used approximately $197.2 million of cash flows from operating activities, received approximately $16.8 million in investing activities and received approximately $179.2 million in financing activities.

Cash flows used in operating activities for the six months ended September 30, 2018, were $197.2 million, compared with cash flows used in operating activities for the six months ended September 30, 2017 of $299.1 million. We continue to invest in inventory and contract assets for new programs which impacts our cash flows from operating activities. During the six months ended September 30, 2018, cash flows used on new programs included approximately $173.0 million and $16.0 million pertaining to the Bombardier Global 7500 program and the Embraer E-Jet, respectively. During the six months ended September 30, 2018, the company received approximately $111.0 million in excess payments from customers resulting in increased accounts payable balances.

Cash flows provided by investing activities for the six months ended September 30, 2018, decreased $28.3 million from the six months ended September 30, 2017. Cash flows provided by investing activities for the six months ended September 30, 2018, included capital expenditures of $24.3 million and proceeds from the sale of assets of $41.0 million. Cash provided by investing activities for the six months ended September 30, 2017, included capital expenditures of $22.8 million and proceeds from the sale of assets of $67.9 million.

Cash flows provided by financing activities for the six months ended September 30, 2018, were $179.2 million, compared with cash flows provided by financing activities for the six months ended September 30, 2017, of $219.7 million.

As of September 30, 2018, $386.2 million was available under our revolving credit facility (the “Credit Facility”) after consideration of covenant limitations.  On September 30, 2018, an aggregate amount of approximately $332.7 million was outstanding under the Credit Facility, all of which was accruing interest at LIBOR plus applicable basis points totaling 3.50% per annum. Amounts repaid under the Credit Facility may be re-borrowed.

At September 30, 2018, there was $85.7 million outstanding under our receivable securitization facility ("Securitization Facility"). Interest rates on the Securitization Facility are based on prevailing market rates for short-term commercial paper,

plus a program fee and a commitment fee. The Securitization Facility's net availability is not impacted by the borrowing capacity of the Credit Facility.

In July 2018, the Company, its subsidiary co-borrowers and guarantors entered into a Tenth Amendment to the Credit Agreement (the “Tenth Amendment” and the existing Credit Agreement as amended by the Tenth Amendment, the "Credit Agreement") and with the Administrative Agent and the Lenders party thereto. Among other things, the Tenth Amendment modifies certain financial covenants and other terms and lowers the capacity upon completion of certain asset sales and will automatically reduce to $700,000 at March 31, 2019. The Tenth Amendment also adds an additional mandatory prepayment provision requiring that the Company prepay the outstanding revolving credit loans as set forth in the Tenth Amendment. The recent divestitures resulted in a reduction of the capacity under the Credit Agreement from $800,000 to $750,000 during the three months ended September 30, 2018.

In July 2017, the Company entered into a Ninth Amendment to the Credit Agreement (the “Ninth Amendment” and the existing Credit Agreement, as amended by the Ninth Amendment, the “Credit Agreement”) with the Administrative Agent and the Lenders party thereto to, among other things, (i) permit the Company to incur High Yield Indebtedness (as defined in the Credit Agreement) in an aggregate principal amount of up to $500.0 million, subject to the Company’s obligations to apply the net proceeds from an offering to repay the outstanding principal amount of the term loans in full; (ii) limit the mandatory prepayment provisions to eliminate the requirement that net proceeds received from the incurrence of Permitted Indebtedness (as defined in the Credit Agreement), including the High Yield Indebtedness, be applied to reduce the revolving credit commitments once the revolving credit commitments have been reduced to $800.0 million; (iii) amend certain covenants and other terms; and (iv) modify the current interest rate and letter of credit pricing tiers.

The Credit Agreement also provided for a variable rate term loan (the "2013 Term Loan"). The Company repaid the outstanding principal amount of the 2013 Term Loan in quarterly installments, on the first business day of each January, April, July and October. The 2013 Term Loan was paid in full with the proceeds from the Senior Notes due 2025 (see below).

In May 2017, the Company entered into an Eighth Amendment to the Third Amended and Restated Credit Agreement (the “Eighth Amendment Effective Date”), among the Company and its lenders to, among other things, (i) eliminate the total leverage ratio financial covenant; (ii) increase the maximum permitted senior secured leverage ratio financial covenant applicable to each fiscal quarter, commencing with the fiscal quarter ended March 31, 2017, and to revise the step-downs applicable to such financial covenant; (iii) reduce the aggregate principal amount of commitments under the revolving line of credit to $850.0 million from $1.0 billion; (iv) modify the maturity date of the term loans so that all of the term loans will mature on March 31, 2019; and (v) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions.

The Company is currently in compliance with all financial covenants under the Credit Agreement. Although the Company does not anticipate any violations of the financial covenants, its ability to comply with these covenants is dependent upon achieving earnings and cash flow projections.

On August 17, 2017, the Company issued $500.0 million principal amount of 7.750% Senior Notes due 2025 (the "2025 Notes"). The 2025 Notes were sold at 100% of principal amount and have an effective interest yield of 7.750%. Interest on the 2025 Notes accrues at the rate of 7.750% per annum and is payable semiannually in cash in arrears on February 15 and August 15 of each year, commencing on February 15, 2018.

The 2025 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2025 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries.

The Company may redeem some or all of the 2025 Notes prior to August 15, 2020, by paying a "make-whole" premium. The Company may redeem some or all of the 2025 Notes on or after August 15, 2020, at specified redemption prices. In addition, prior to August 15, 2020, the Company may redeem up to 35% of the 2025 Notes with the net proceeds of certain equity offerings at a redemption price equal to 107.750% of the aggregate principal amount plus accrued and unpaid interest, if any, subject to certain limitations set forth in the indenture governing the 2025 Notes (the "2025 Indenture").

The Company is obligated to offer to repurchase the 2025 Notes at a price of (i) 101% of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events and (ii) 100% of their principal amount plus

51

Management's Discussion and Analysis of

(continued)

accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The 2025 Indenture contains covenants that, among other things, limit the Company's ability and the ability of any of the Guarantor Subsidiaries to (i) grant liens on its assets; (ii) make dividend payments, other distributions or other restricted payments; (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments; (iv) enter into sale and leaseback transactions; (v) merge, consolidate, transfer or dispose of substantially all of their assets; (vi) incur additional indebtedness; (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries; and (viii) enter into transactions with affiliates.

The expected future cash flows for the next five years for long-term debt, leases and other obligations are as follows:

	Payments Due by Period (in thousands)
Contractual Obligations	Total		Less than 1 year		1-3 years		4-5 years		More than 5 years
Debt principal (1)	$	1,643,101	$	14,993	$	814,382	$	305,410	$	508,316
Debt interest (2)	324,339		74,360		138,140		85,964		25,875
Operating leases	114,203		25,485		35,514		19,332		33,872
Purchase obligations	1,770,547		1,356,729		306,330		80,542		26,946
Total	$	3,852,190	$	1,471,567	$	1,294,366	$	491,248	$	595,009

(1) Included in the Company’s condensed consolidated balance sheet at September 30, 2018.

(2) Includes fixed-rate interest only.

The above table excludes unrecognized tax benefits of $17.4 million as of September 30, 2018, since we cannot predict with reasonable certainty the timing of cash settlements with the respective taxing authorities.

For the fiscal year ending March 31, 2019, the Company is not required to make minimum contributions to its U.S. defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 and the Pension Protection Act of 2006.

We believe that cash flows from operations and borrowings under the Credit Facility will be sufficient to meet anticipated cash requirements for our current operations for the foreseeable future. However, we are continuously evaluating various acquisition and divestiture opportunities. As a result, we currently are pursuing the potential purchase of a number of candidates. In the event that more than one of these transactions are successfully consummated, the availability under the Credit Facility might be fully utilized and additional funding sources may be needed. There can be no assurance that such funding sources will be available to us on terms favorable to us, if at all.

Critical Accounting Policies

The Company's critical accounting policies are discussed in Management's Discussion and Analysis of Financial Condition and Results of Operations and notes accompanying the condensed consolidated financial statements that appear in the Annual Report on Form 10-K for the fiscal year ended March 31, 2018. Except as otherwise disclosed in the condensed consolidated financial statements and accompanying notes included in this report, there were no material changes subsequent to the filing of the Annual Report on Form 10-K for the fiscal year ended March 31, 2018, in the Company's critical accounting policies or in the assumptions or estimates used to prepare the financial information appearing in this report.

Forward-Looking Statements

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 relating to our future operations and prospects, including statements that are based on current projections and expectations about the markets in which we operate, and our beliefs concerning future performance and capital requirements based upon current available information. Such statements are based on our beliefs as well as assumptions made by and information

currently available to us. When used in this document, words like “may,” “might,” “will,” “expect,” “anticipate,” “believe,” “potential,” "plan," "estimate," and similar expressions are intended to identify forward-looking statements. Actual results could differ materially from our current expectations. For example, there can be no assurance that additional capital will not be required or that additional capital, if required, will be available on reasonable terms, if at all, at such times and in such amounts as may be needed by us. In addition to these factors, among other factors that could cause actual results to differ materially are uncertainties relating to our ability to execute on our restructuring plans, the integration of acquired businesses, divestitures of our business, general economic conditions affecting our business, dependence of certain of our businesses on certain key customers as well as competitive factors relating to the aviation industry. For a more detailed discussion of these and other factors affecting us, see the risk factors described in our Annual Report on Form 10-K for the fiscal year ended March 31, 2018, filed with the SEC on May 22, 2018.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

For information regarding our exposure to certain market risks, see “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the fiscal year ended March 31, 2018. There has been no material change in this information during the period covered by this report.

Item 4. Controls and Procedures.

(a) Evaluation of disclosure controls and procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports pursuant to the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of September 30, 2018, we completed an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2018.

(b) Changes in internal control over financial reporting.

There were no changes that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

BASIS OF PRESENTATION AND ORGANIZATION

The accompanying unaudited condensed consolidated financial statements of Triumph Group, Inc. (the "Company") have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position and cash flows. The results of operations for the three and six months ended September 30, 2018, are not necessarily indicative of results that may be expected for the year ending March 31, 2019. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the fiscal 2018 audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended March 31, 2018, filed with the Securities and Exchange Commission (the "SEC") on May 22, 2018.

The Company designs, engineers, manufactures, repairs and overhauls a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. The Company serves a broad, worldwide spectrum of the aviation industry, including original equipment manufacturers of commercial, regional, business, and military aircraft and aircraft components, as well as commercial and regional airlines and air cargo carriers.

The Company has reclassified certain prior period amounts in order to conform to the current period presentation.

Standards Recently Implemented

Adoption of ASU 2014-09

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) that supersedes Accounting Standards Codification ("ASC") Topic 605 (“legacy GAAP”). Subsequently, the FASB issued several updates to ASU 2014-09, which are pending content or otherwise codified in ASC Topic 606 (“ASC 606”). ASU 2014-09 includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40 (“ASC 340-40”). The Company adopted ASC 606 using the modified retrospective method (“method”) effective as of April 1, 2018 (“date of initial application”). Under this method, the cumulative effect of the adoption of ASC 606 is recognized as an adjustment to retained earnings on the date of initial application (“Transition Adjustment”), and the comparative financial statements for prior periods are not adjusted and continue to be reported under legacy GAAP. The Transition Adjustment was a decrease to retained earnings of $584,900. Financial information for fiscal years 2019 and 2018 is presented under ASC 606 and under legacy GAAP, respectively. The tables below reflect adjusted fiscal year 2019 financial statement amounts as if the Company had been reporting under legacy GAAP for items that are materially different.

The adoption of ASC 606 does not impact the Company's cash flows or the underlying economics of the Company's contracts with customers. However, the pattern and timing of revenue and profit recognition, as well as financial statement presentation and disclosures, has changed.

The significant changes and the qualitative and quantitative impact of the adoption of ASC 606 are noted below:

a.Revenue from Contracts with Customers

Generally, the Company no longer uses the units-of-delivery method, and the historical use of contract blocks to define contracts for accounting purposes has been replaced by accounting contracts as identified under ASC 606. The Company's accounting contracts under ASC 606 are for the specific number of units for which orders have been received, which is typically for fewer units than what was used to define contract blocks under legacy GAAP. In most of the Company's contracts, the customer has options or requirements to purchase additional products and services that do not represent material rights since the options are at their standalone pricing.

The primary effect of the Company’s adoption of ASC 606 (outside of the Aerospace Structures segment) was to recognize revenue over time for certain of its contracts, which is a change from recognition based on shipping terms under the legacy GAAP accounting policy.

b.Capitalized Preproduction Costs

Under legacy GAAP, certain capitalized preproduction costs were deferred over the life of the contract block; in certain situations this is not permitted under ASC 606. Accordingly, capitalized preproduction costs of $865,843 (pre-tax), net of previously recognized forward loss reserves of $343,983 (pre-tax), were eliminated, resulting in a decrease to retained earnings as of April 1, 2018.

c.Contract Assets and Contract Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract assets in the amount of $565,414 were established in the Transition Adjustment.

Contract liabilities primarily represent cash received that is in excess of revenues recognized and is contingent upon the satisfaction of performance obligations. Contract liabilities in the amount of $288,287 were established in the Transition Adjustment, which reflects consideration received prior to the date of initial application that previously represented customer advances and additional forward losses due to change in block sizes. This liability will be recognized as revenue earlier if the options are not fully exercised, or immediately if the contract is terminated prior to the options being fully exercised.

d.Contract Costs

The Company’s accounting for preproduction, tooling and certain other costs has not changed since these costs generally do not fall within the scope of ASC 340-40, however certain related assets have been reclassified from inventory to property and equipment as they are costs to fulfill obligations beyond 1 year. Incurred production costs for anticipated contracts (satisfaction of performance obligations, which have commenced because the Company expects the customer to exercise options) continue to be classified as inventory.

e.Practical Expedients

The Company has adopted ASC 606 only for contracts that were not substantially completed under legacy GAAP on the date of initial application. For these contracts, the Company has reflected the aggregate effect of all modifications executed prior to the date of initial application when identifying satisfied and unsatisfied performance obligations, for determining the transaction price and for allocating the transaction price.

The following tables summarize the impacts of adopting ASC 606 on the Company’s consolidated financial statements for the three and six months ended September 30, 2018.

Adoption of ASU 2017-07

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires an employer to report the service cost component of net periodic pension benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period, with other cost components presented separately from the service cost component and outside of income from operations. ASU 2017-07 also allows only the service cost component of net periodic pension benefit cost to be eligible for capitalization when applicable. ASU 2017-07 was effective for years beginning after December 15, 2017. The Company adopted this standard on April 1, 2018, applying the presentation requirements retrospectively. We elected to apply the practical expedient, which allows us to reclassify amounts disclosed previously in the employee benefit plans note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. Provisions related to presentation of the service cost component eligibility for capitalization were applied prospectively.

The effect of the retrospective presentation change related to the net periodic benefit cost of our defined benefit pension and postretirement plans on our condensed consolidated statements of operations was as follows:

During the first quarter of the fiscal year ended March 31, 2019, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to an inseparable change in estimate from a change in accounting principles. This charge is presented on the accompanying condensed consolidated statements of operations within "Cost of sales."

Adoption of ASU 2017-12

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which expands component and fair value hedging, specifies the presentation of the effects of hedging instruments, and eliminates the separate measurement and presentation of hedge ineffectiveness. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU 2017-12 as of April 1, 2018. The adoption of ASU 2017-12 did not have a material impact on the Company’s condensed consolidated financial statements.

Standards Issued Not Yet Implemented

In February 2018, the FASB issued ASU 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The guidance in ASU 2018-02 allows an entity to elect to reclassify the stranded tax effects related to the Tax Cuts and Jobs Act of 2017 (the “Act”) from accumulated other comprehensive income into retained earnings. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material effect on the Company’s condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). The guidance in ASU 2016-02 aims to increase transparency and comparability across organizations by requiring lease assets and lease liabilities to be recognized on the balance sheet as well as key information to be disclosed regarding lease arrangements. The amendments in ASU 2016-02 are effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU 2018-11, Leases: Targeted Improvements. Among other things, this ASU provides entities with a transition option to recognize the cumulative-effect adjustment from the modified retrospective application to the opening balance of retained earnings in the period of adoption rather than the earliest period presented in the financial statements. We currently expect to adopt ASU 2016-02, as updated, effective April 1, 2019. The Company has not yet selected a transition method. The adoption of this new accounting standard will result in an increase in the recognition of right-of-use assets and lease liabilities. However, the Company is continuing to evaluate the impact of adopting this new accounting guidance and, therefore, cannot reasonably estimate the impact on the results of operations or cash flows at this time.

Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The Company makes estimates of the cost of satisfying the performance obligations in its contracts that may extend over many years. Cost estimates reflect currently available information and the impact of any changes to cost estimates, based upon the facts and circumstances, are recorded in the period in which they become known.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. The Company’s contracts with customers are typically for products and services to be provided at fixed stated prices but may also include variable consideration. Variable consideration may include, but is not limited to, unpriced contract modifications; cost sharing provisions; incentives and awards; non-warranty claims and assertions; provisions for non-conformance and rights to return; or other payments to, or receipts from, customers. The Company estimates the variable consideration using the expected value or the most likely amount based upon the facts and circumstances, available data and trends, and the history of resolving variability with specific customers.

The Company regularly commences work and incorporates customer-directed changes prior to negotiating pricing terms for engineering work, product modifications, and other statements of work. The Company's contractual terms typically provide for price negotiations after certain customer-directed changes have been accepted by the Company. Prices are estimated and related costs are deferred until they are contractually agreed upon with the customer. When a contract is modified, the Company evaluates whether additional distinct products and services have been promised and whether allocation of consideration is necessary. If not, the modification is treated as a change to the performance obligations within the existing contract, or otherwise accounted for as a new contract prospectively.

The Company allocates the consideration for a contract to the performance obligations on the basis of their relative standalone selling price. The Company estimates the likelihood of the amount of options that the customer is going to exercise when assessing the existence of performance obligations with respect to this allocation or for assessing the impact of loss contracts. The Company typically provides warranties on all of the Company's products and services. Warranties are typically not priced separately and customers cannot purchase them independently of the products or services under contract; therefore, warranties do not create performance obligations. Triumph's warranties generally provide assurance to the Company's customers that the products or services meet the specifications in the contract. In the event that there is a warranty claim because of a covered material or workmanship issue, the Company may be required to pay the customer for repairs or to perform the repair. Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These costs are accrued at the time of the sale and are recorded as cost of sales. These estimates are established using historical information on the nature, frequency, and the cost experience of warranty claims. In the case of new development products or new customers, the Company also considers other factors such as the type and nature of the new product or new customer, among others; these considerations involve the use of management judgment. Actual results could differ from those estimates and assumptions.

For the three months ended September 30, 2018, cumulative catch-up adjustments from changes in estimates, including changes in forward loss estimates, increased net sales, operating loss, net loss, and loss per share by approximately $3,459, $(10,191), $(10,191) and $(0.21), net of tax, respectively. For the three months ended September 30, 2017, cumulative catch-up adjustments from changes in estimates decreased operating loss, net loss and loss per share by approximately $8,416, $6,733 and $0.14, net of tax, respectively.

For the six months ended September 30, 2018, cumulative catch-up adjustments from changes in estimates, including changes in forward loss estimates, decreased net sales and increased operating loss, net loss and loss per share by approximately $(3,292), $(12,968), $(12,968) and $(0.26), net of tax, respectively. In addition, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to a change in estimate from a change in accounting principles, which is presented on the accompanying condensed consolidated statements of operations within "Cost of sales." For the six months ended September 30, 2017, cumulative catch-up adjustments from changes in estimates decreased operating loss, net loss and loss per share by approximately $7,916, $6,333 and $0.13, net of tax, respectively.

Revenue Recognition

A significant majority of the Company’s revenues are from long-term supply agreements with various aerospace manufacturers. The Company participates in its customers’ programs by providing design, development, manufacturing, and support services across its various segments. During the early stages of a program, this frequently involves non-recurring design and development services, including tooling. As the program matures, the Company provides recurring manufacturing of products in accordance with customer design and schedule requirements. Many contracts include clauses that provide sole supplier status to the Company for the duration of the program’s life. The Company's long-term supply agreements typically include fixed price volume-based terms and require the satisfaction of performance obligations for the duration of the program’s life.

The identification of an accounting contract with a customer and the related promises requires an assessment of each party’s rights and obligations regarding the products or services to be transferred, including an evaluation of termination clauses and presently enforceable rights and obligations. In general, these long-term supply agreements are legally governed by Master Supply Agreements (or General Terms & Agreement) under which special business provisions (or work package agreements) define specific program requirements. Purchase orders (or authorizations to proceed) are issued under these agreements to reflect presently enforceable rights and obligations for the units of products and services being purchased. The units for accounting purposes (“accounting contract”) are typically determined by the purchase orders. Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. A single program may result in multiple contracts for accounting purposes, and within the respective contracts, non-recurring work elements and recurring work elements may result in multiple performance obligations. The Company generally contracts directly with its customers and is the principal in all current contracts.

Management considers a number of factors when determining the existence of a contract and the related performance obligations that include, but are not limited to: the nature and substance of the business exchange; the contractual terms and conditions; the promised products and services; the termination provisions in the contract; the presently enforceable rights and obligations of the parties to the contract; the nature and execution of the customer’s ordering process and how the Company is authorized to perform work; whether the promised products and services are capable of being distinct and are distinct within the context of the contract; as well as how and when products and services are transferred to the customer.

Revenue is recognized when, or as, control of promised products or services transfers to a customer and is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those products or services. Revenue is recognized over time as work progresses when the Company is entitled to the reimbursement of costs plus a reasonable profit for work performed for which the Company has no alternate use or when performing work on a customer-owned asset. For these performance obligations that are satisfied over time, the Company generally recognizes revenue using an input method with revenue amounts being recognized proportionately as costs are incurred relative to the total expected costs to satisfy the performance obligation. The Company believes that costs incurred as a portion of total estimated costs is an appropriate measure of progress toward satisfaction of the performance obligation since this measure reasonably depicts the progress of the work effort.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer (which is generally based on shipping terms). For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Shipping and handling costs are not considered performance obligations and are included in cost of sales as incurred.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. A subset of the Company’s current contracts include significant financing components because the timing of the transfer of the underlying products and services under contract are at the customers’ discretion. The Company's contracts with customers generally require payment under normal commercial terms after delivery. Payment terms are typically within 30 to 120 days of delivery. The total transaction price is allocated to each of the identified performance obligations using the relative standalone selling price to reflect the amount the Company expects to be entitled for transferring the promised products and services to the customer. A majority of the Company’s agreements with customers include options for future purchases. As allowed by ASC 606, for all of its contracts the Company has elected to exclude sales and other similar taxes from the transaction price since the Company generally is not subject to collecting sales tax. As a result, the Company's collections from customers for these taxes are on a net basis.

Standalone selling price is the price at which the Company would sell a promised good or service separately to a customer. Standalone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When standalone selling prices for the Company’s products and services are generally not observable, the Company uses either the “Expected Cost plus a Margin” or "Adjusted Market Assessment" approaches to determine standalone selling price. Expected costs are typically derived from the available periodic forecast information. If a contract modification changes the overall transaction price of an existing contract, the Company allocates the new transaction price on the basis of the relative standalone selling prices of the performance obligations, and cumulative adjustments, if any, are recorded in the current period.

The Company also identifies and estimates variable consideration for contractual provisions such as unpriced contract modifications, cost sharing provisions, and other receipts or payments to customers. The timing of satisfaction of performance obligations and actual receipt of payment from a customer may differ and affects the balances of the contract assets and liabilities.

For contracts that are deemed to be loss contracts, the Company establishes forward loss reserves for total estimated costs that are in excess of total estimated consideration in the period in which they become known. The Company records forward loss reserves for all performance obligations in the aggregate for the accounting contract.

Included in net sales of Integrated Systems and Aerospace Structures is the non-cash amortization of acquired contract liabilities that were recognized as fair value adjustments through purchase accounting from various acquisitions. For the three months ended September 30, 2018 and 2017, the Company recognized $16,804 and $27,898 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations. For the six months ended September 30, 2018 and 2017, the Company recognized $34,038 and $57,371 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations.

Disaggregation of Revenue

The Company disaggregates revenue based on the method of measuring satisfaction of the performance obligation either over time or at a point in time. Additionally, the Company disaggregates revenue based upon the end market where products and services are transferred to the customer. The Company’s principal operating segments and related revenue are noted in Note 13, Segments.

The following table shows disaggregated net sales satisfied overtime and at a point in time (excluding intercompany sales) for the three and six months ended September 30, 2018:

Concentration of Credit Risk

The Company’s trade accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from Boeing (representing commercial, military and space) represented approximately 15% and 10% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Gulfstream represented approximately 7% and 16% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Bombardier represented approximately 12% and 1% as of September 30, 2018 and March 31, 2018, respectively. The Company had no other concentrations of credit risk of more than 10%.

Sales to Boeing for the six months ended September 30, 2018, were $527,896, or 31% of net sales, of which $110,971, $410,133, and $6,792 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Boeing for the six months ended September 30, 2017, were $507,330, or 33% of net sales, of which $105,304, $397,817 and $4,209 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

Sales to Gulfstream for the six months ended September 30, 2018, were $174,805, or 10% of net sales, of which $1,065, $173,437, and $303 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Gulfstream for the six months ended September 30, 2017, were $198,525, or 13% of net sales, of which $654, $197,674, and $197 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries.

Stock-Based Compensation

The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for the three months ended September 30, 2018 and 2017, was $3,266 and $3,459, respectively. Stock-based compensation expense for the six months ended September 30, 2018 and 2017, was $5,728 and $3,418, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to employees. Upon the exercise of stock options or vesting of restricted stock, the Company first transfers treasury stock, then issues new shares.

Intangible Assets

The components of intangible assets, net, are as follows:

	September 30, 2018
	Weighted- Average Life	Gross Carrying Amount		Accumulated Amortization			Net

Amortization expense for the three months ended September 30, 2018 and 2017, was $13,203 and $14,550, respectively. Amortization expense for the six months ended September 30, 2018 and 2017, was $26,436 and $29,375, respectively.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its divestitures (see Note 3).

Warranty Reserves

A reserve has been established to provide for the estimated future cost of warranties on our delivered products. The Company periodically reviews the reserves and adjustments are made accordingly. A provision for warranty on products delivered is made on the basis of historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The majority of the Company's agreements include a three-year warranty, although certain programs have warranties up to twenty years. The warranty reserves as of September 30, 2018 and March 31, 2018, were $65,158 and $69,588, respectively.

Supplemental Cash Flow Information

The Company received income tax refunds, net of payments of $7,120 and paid $5,133 for income taxes, net of refunds, for the six months ended September 30, 2018 and 2017, respectively.

The Company made interest payments of $38,587 and $31,507 for the six months ended September 30, 2018 and 2017, respectively.

During the six months ended September 30, 2018 and 2017, the Company financed $372 and $1,153, respectively, of property and equipment additions through capital leases.

As of September 30, 2018, the Company remains able to purchase an additional 2,277,789 shares under the existing stock repurchase program. However, there are certain restrictions placed on the repurchase program by the Company's lenders that prevent any repurchases at this time.

INVENTORIES

INVENTORIES

Inventories are stated at the lower of cost (average-cost or specific-identification methods) or market. The components of inventories are as follows:

	September 30, 2018		March 31, 2018
Raw materials	$	61,987	$	69,069
Work-in-process, including manufactured and purchased components	351,748		1,591,952
Finished goods	63,716		95,234
Rotable assets	56,132		58,060
Less: unliquidated progress payments	—		(387,146		)
Total inventories	$	533,583	$	1,427,169

At March 31, 2018, work-in-process inventory previously included capitalized preproduction costs on newer development programs. Capitalized preproduction costs include non-recurring engineering, planning and design, including applicable overhead, incurred before production is manufactured on a regular basis. Significant customer-directed work changes can also cause preproduction costs to be incurred. These costs are typically recovered over a contractually determined number of ship set deliveries.

Following the adoption of ASU 2014-09, the capitalized preproduction costs and forward loss provisions associated with these programs were recognized in the transition adjustment. At March 31, 2018, the balance of development program inventory, composed principally of capitalized preproduction costs, excluding progress payments related to the Company's contracts with Bombardier for the Global 7500 program ("Bombardier") and Embraer for the second generation E-Jet program ("Embraer") was as follows:

	March 31, 2018
	Inventory		Capitalized Preproduction		Forward Loss Provision			Total Inventory, net
Bombardier	$	321,780	$	685,503	$	(343,000	)	$	664,283

During the fiscal year ended March 31, 2016, the Company recorded a $399,758 forward loss charge for the Bombardier Global 7500 wing program ("Global 7500"). Under our contract for the Bombardier Global 7500, the Company has the right to design, develop and manufacture wing components for the Global 7500 program. The Global 7500 contract provides for fixed pricing and requires the Company to fund certain up-front development expenses, with certain milestone payments made by Bombardier.

The Global 7500 program charge resulted in the impairment of previously capitalized preproduction costs due to the combination of cost recovery uncertainty, higher than anticipated non-recurring costs and increased forecasted costs on recurring production. The increases in costs were driven by several factors, including changing technical requirements, increased spending on the design and engineering phase of the program, and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers.

The Global 7500 program has continued to incur costs since March 2016 in support of the development and transition to production.

In May 2017, Triumph Aerostructures and Bombardier entered into a comprehensive settlement agreement that resolved all outstanding commercial disputes between them, including all pending litigation, related to the design, manufacture and supply of wing components for the Global 7500 business aircraft. The settlement reset the commercial relationship between the companies and allowed each company to better achieve its business objectives going forward.

Further cost increases or an inability to meet revised recurring cost forecasts on the Global 7500 program may result in additional forward loss reserves in future periods, while improvements in future costs compared with current estimates may result in favorable adjustments if forward loss reserves are no longer required.

The Company is still in the early production stages for the Bombardier and Embraer programs, as these aircrafts are scheduled to enter service in fiscal 2019. Transition of these programs from development to recurring production levels is dependent upon the success of the programs achieving flight testing and certification, as well as the ability of the Bombardier and Embraer programs to generate acceptable levels of aircraft sales. The failure to achieve these milestones and level of sales or significant cost overruns may result in additional forward losses.

Revolving Credit Facility

In July 2018, the Company, its subsidiary co-borrowers and guarantors entered into a Tenth Amendment to the Credit Agreement (the “Tenth Amendment” and the existing Credit Agreement as amended by the Tenth Amendment, the "Credit Agreement") and with the Administrative Agent and the Lenders party thereto. Among other things, the Tenth Amendment modifies certain financial covenants and other terms and lowers the capacity upon completion of certain asset sales and will automatically reduce to $700,000 at March 31, 2019. The Tenth Amendment also adds an additional mandatory prepayment provision requiring that the Company prepay the outstanding revolving credit loans as set forth in the Tenth Amendment. The recent divestitures resulted in a reduction of the capacity under the Credit Agreement from $800,000 to $750,000 during the three months ended September 30, 2018.

In connection with the Tenth Amendment to the Credit Agreement, the Company incurred $1,694 of financing costs. These costs, along with the $8,961 of unamortized financing costs subsequent to the Ninth Amendment, are being amortized over the remaining term of the Credit Agreement. In accordance with the reduction in the capacity of the Credit Agreement, the Company wrote off a proportional amount of unamortized financing fees existing prior to the Tenth Amendment.

In July 2017, the Company entered into a Ninth Amendment to the Credit Agreement (the “Ninth Amendment” and the existing Credit Agreement, as amended by the Ninth Amendment, the “Credit Agreement”) with the Administrative Agent and the Lenders party thereto to, among other things: (i) permit the Company to incur High Yield Indebtedness (as defined in the Credit Agreement) in an aggregate principal amount of up to $500,000, subject to the Company’s obligations to apply the net proceeds from an offering to repay the outstanding principal amount of the term loans in full; (ii) limit the mandatory prepayment provisions to eliminate the requirement that net proceeds received from the incurrence of Permitted Indebtedness (as defined in the Credit Agreement), including the High Yield Indebtedness, be applied to reduce the revolving credit commitments once the revolving credit commitments have been reduced to $800,000; (iii) amend certain covenants and other terms; and (iv) modify the current interest rate and letter of credit pricing tiers.

In May 2017, the Company entered into an Eighth Amendment to the Credit Agreement, among the Company and its lenders to, among other things: (i) eliminate the total leverage ratio financial covenant; (ii) increase the maximum permitted senior secured leverage ratio financial covenant applicable to each fiscal quarter, commencing with the fiscal quarter ended March 31, 2017, and to revise the step-downs applicable to such financial covenant; (iii) reduce the aggregate principal amount of commitments under the revolving line of credit to $850,000 from $1,000,000; (iv) modify the maturity date of the term loans so that all of the term loans will mature on March 31, 2019; and (v) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions.

The obligations under the Credit Agreement and related documents are secured by liens on substantially all assets of the Company and its domestic subsidiaries pursuant to a Second Amended and Restated Guarantee and Collateral Agreement, dated as of November 19, 2013, among the administrative agent, the Company and the subsidiaries of the Company party thereto.

Pursuant to the Credit Agreement, the Company can borrow, repay and re-borrow revolving credit loans, and cause to be issued letters of credit, in an aggregate principal amount not to exceed $750,000 outstanding at any time. The Credit Agreement bears interest at either: (i) London Interbank Offered Rate (LIBOR) plus between 1.50% and 3.50%; (ii) the prime rate; or (iii) an overnight rate at the option of the Company. The applicable interest rate is based upon the Company’s ratio of total indebtedness to earnings before interest, taxes, depreciation and amortization. In addition, the Company is required to pay a commitment fee of 0.50% on the unused portion of the Credit Agreement. The Company’s obligations under the Credit Agreement are guaranteed by the Company’s domestic subsidiaries.

At September 30, 2018, there were $332,661 in borrowings and $31,156 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. At March 31, 2018, there were $112,887 in borrowings and $30,641 in letters of credit outstanding under the Revolving Line of Credit provisions of the Credit Agreement, primarily to support insurance policies. The level of unused borrowing capacity under the Revolving Line of Credit provisions of the Credit Agreement varies from time to time depending in part upon its compliance with financial and other covenants set forth in the related agreement. The Credit Agreement contains certain affirmative and negative covenants, including limitations on specified levels of indebtedness to earnings before interest, taxes, depreciation and amortization, and interest coverage requirements, and includes limitations on, among other things, liens, mergers, consolidations, sales of assets, and incurrence of debt. If an event of default were to occur under the Credit Agreement, the lenders would be entitled to declare all amounts borrowed under it immediately due and payable. The occurrence of an event of default under the Credit Agreement could also cause the acceleration of obligations under certain other agreements. The Company is currently in compliance with all such covenants. Although the Company does not anticipate any violations of the financial covenants, its ability to comply with these covenants is dependent upon achieving earnings and cash flow projections. As of September 30, 2018, the Company had borrowing capacity under this agreement of $386,183 after reductions for borrowings, letters of credit outstanding under the facility and consideration of covenant limitations.

The Credit Agreement also provided for a variable rate term loan (the "2013 Term Loan"). The Company repaid the outstanding principal amount of the 2013 Term Loan in quarterly installments, on the first business day of each January, April, July and October. During August 2017, the 2013 Term Loan was paid in full with the proceeds from the Senior Notes due 2025.

The Company previously maintained an interest rate swap agreement to reduce its exposure to interest on the variable rate portion of its long-term debt. In conjunction with the repayment of the 2013 Term Loan, the Company terminated the interest rate swap receiving $280 upon settlement.

Receivables Securitization Facility

In November 2017, the Company amended the Securitization Facility decreasing the purchase limit from $225,000 to $125,000 and extending the term through November 2020. In connection with the Securitization Facility, the Company sells on a revolving basis certain trade accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. As of September 30, 2018, the maximum amount available under the Securitization Facility was $125,000. Interest rates are based on LIBOR plus a program fee and a commitment fee. The program fee is 0.13% on the amount outstanding under the Securitization Facility. Additionally, the commitment fee is 0.50% on 100.00% of the maximum amount available under the Securitization Facility. The Company secures its trade accounts receivable, which are generally non-interest bearing, in transactions that are accounted for as borrowings pursuant to the Transfers and Servicing topic of the ASC 860.

The agreement governing the Securitization Facility contains restrictions and covenants, including limitations on the making of certain restricted payments; creation of certain liens; and certain corporate acts such as mergers, consolidations and the sale of all or substantially all of the Company's assets.

Senior Notes Due 2021

On February 26, 2013, the Company issued $375,000 principal amount of 4.875% Senior Notes due 2021 (the "2021 Notes"). The 2021 Notes were sold at 100% of principal amount and have an effective interest yield of 4.875%. Interest on the 2021 Notes accrues at the rate of 4.875% per annum and is payable semiannually in cash in arrears on April 1 and October 1 of each year, commencing on October 1, 2013.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

The Company follows the Income Taxes topic of ASC 740, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (the “Act”). The Act introduced tax reform that reduced the current corporate federal income tax rate from 35% to 21%, among other changes. The Act makes broad and complex changes to the U.S. tax code, and it will take time to fully evaluate the impact of these changes on the Company. The Company has prepared a reasonable estimate around the impact of the Act and has recorded a provisional impact (as described in the SEC's Staff Accounting Bulletin 118) to the tax provision in the period ended March 31, 2018. While the Company has computed and recorded these provisional amounts, these will be finalized within the established measurement period (not to exceed one year) as additional data and information is gathered. The Company determined that the amounts recorded are provisional as adjustments may occur due to additional guidance from the Internal Revenue Service and as certain tax positions are finalized when the Company files its fiscal 2018 tax returns. As of September 30, 2018, the Company has not made material revisions to the provisional tax impact of the Act. Any revisions will be included as an adjustment to the tax expense in the period in which the amounts are determined.

The Company is still evaluating the effects of the Act’s global intangible low-taxed income (“GILTI”) provisions and has not adopted an accounting policy on whether the Company will account for GILTI as a period expense or record deferred taxes on temporary basis differences expected to reverse as GILTI in future years. The Company's accounting for the effects of the GILTI provision is incomplete; however, the Company has included estimated GILTI tax related to current year operations in the Company's annualized effective tax rate and has not provided additional GILTI on deferred items.

The Act also introduces base erosion and anti-abuse tax provisions (“BEAT”) for companies that meet certain thresholds by effectively excluding deductions on certain payments to foreign related entities. Although the Company's analysis of the tax effects of the BEAT provision is incomplete, the Company does not expect to be subject to the tax.

The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of income tax expense. As of September 30, 2018 and March 31, 2018, the total amount of accrued income tax-related interest and penalties was $356 and $327, respectively.

As of September 30, 2018 and March 31, 2018, the total amount of unrecognized tax benefits was $17,374 and $11,532, respectively, most of which would impact the effective rate, if recognized. The Company does not anticipate that total unrecognized tax benefits will be reduced in the next 12 months.

As of September 30, 2018, the Company has a valuation allowance against principally all of its net deferred tax assets given insufficient positive evidence to support the realization of the Company’s deferred tax assets.  The Company intends to continue maintaining a valuation allowance on its deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances.  A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the release is recorded.  However, the exact timing and amount of the reduction in its valuation allowance is unknown at this time and will be subject to the earnings level the Company achieves during fiscal 2019 as well as the Company's income in future periods.

The effective income tax rate for the three months ended September 30, 2018, was (2.2)% as compared with 17.6% for the three months ended September 30, 2017. For the three months ended September 30, 2018, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

The effective income tax rate for the six months ended September 30, 2018, was (1.6)% as compared with 20.0% for the six months ended September 30, 2017. For the six months ended September 30, 2018, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

With few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations for fiscal years ended before March 31, 2014, or foreign income tax examinations by tax authorities for fiscal years ended before March 31, 2011.

As of September 30, 2018, the Company is subject to examination in one state jurisdiction and one foreign jurisdiction. The Company has filed appeals in a prior state examination related to fiscal years ended March 31, 1999 through March 31, 2005. Because of net operating losses acquired as part of the acquisition of Vought, the Company is subject to U.S. federal income tax examinations and various state jurisdictions for the years ended December 31, 2001 and after, related to previously filed Vought tax returns. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years.

PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

Retirement Benefits [Abstract]

PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

The Company sponsors several defined benefit pension plans covering some of its employees. Certain employee groups are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans based upon their service to the Company or years of service accrued under the defined benefit pension plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company’s policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under U.S. government regulations, by making payments into a separate trust.

In addition to the defined benefit pension plans, the Company provides certain healthcare and life insurance benefits for eligible retired employees. Such benefits are unfunded. Employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age and years of service requirements. Election to participate for some employees must be made at the date of retirement. Qualifying dependents at the date of retirement are also eligible for medical coverage. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. From time to time, changes have been made to the benefits provided to various groups of plan participants. Premiums charged to most retirees for medical coverage prior to age 65 are based on years of service and are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans and a Medicare carve-out.

In accordance with the Compensation – Retirement Benefits topic of ASC 715, the Company has recognized the funded status of the benefit obligation as of the date of the last re-measurement, on the accompanying condensed consolidated balance sheets. The funded status is measured as the difference between the fair value of the plan’s assets and the pension benefit obligation or accumulated postretirement benefit obligation, of the plan. In order to recognize the funded status, the Company determined the fair value of the plan assets. The majority of the plan assets are publicly traded investments, which were valued based on the market price as of the date of re-measurement. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on our evaluation of data from fund managers and comparable market data.

Segment Reporting [Abstract]

SEGMENTS

SEGMENTS

The Company has three reportable segments: Integrated Systems, Aerospace Structures and Product Support. The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate performance of its segments and allocate resources.

Integrated Systems consists of the Company’s operations that provide integrated solutions, including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs.  Capabilities include hydraulic, mechanical and electromechanical actuation, power and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units and Full Authority Digital Electronic Control fuel systems; hydro-mechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options.

Aerospace Structures consists of the Company’s operations that supply commercial, business, regional and military manufacturers with large metallic and composite structures. Products include wings, wing boxes, fuselage panels, horizontal and vertical tails and sub-assemblies such as floor grids. Aerospace Structures also has the capability to engineer detailed structural designs in metal and composites. It also includes the Company’s operations that produce close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities. Capabilities include complex machining; gear manufacturing; sheet metal fabrication; forming; advanced composite and interior structures; joining processes such as welding, autoclave bonding and conventional mechanical fasteners; and a variety of special processes, including super plastic titanium forming, aluminum and titanium chemical milling, and surface treatments. As described in Note 1, during the first quarter of the fiscal year ended March 31, 2019, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to an inseparable change in estimate from a change in accounting principles. This charge is included in Aerospace Structures operating income and is excluded from Segment Adjusted EBITDAP.

Product Support consists of the Company’s operations that provide full life cycle solutions for commercial, regional and military aircraft. The Company’s extensive product and service offerings include full post-delivery value chain services that simplify the MRO supply chain. Through its line maintenance, component MRO and postproduction supply chain activities, Product Support is positioned to provide integrated planeside repair solutions globally. Capabilities include fuel tank repair, metallic and composite aircraft structures, nacelles, thrust reversers, interiors, auxiliary power units and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories.

Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments, including loss on divestitures of $17,837 for the six months ended September 30, 2018.

The Company does not accumulate net sales information by product or service or groups of similar products and services and, therefore, the Company does not disclose net sales by product or service because to do so would be impracticable.

16.    RESTRUCTURING COSTS

During the fiscal years ended March 31, 2017 and 2016, the Company committed to restructuring plans involving certain of its businesses, as well as the consolidation of certain of its facilities. These plans are nearing completion, and as a result, the Company will have reduced its footprint by approximately 4.3 million square feet, will have reduced head count by approximately 2,500 employees and will have amended certain contracts. The Company originally estimated that it would record aggregate pre-tax charges of $195,000 to $210,000 related to these programs, which represent employee termination benefits, contract termination costs, accelerated depreciation, and facility closure and other exit costs. These charges have resulted in cash outlays and will continue to do so until the completion of the related programs. As of September 30, 2018, the Company has updated its estimate of the expected aggregate pre-tax charge to $204,400 upon completion of the restructuring and is considering whether additional programs, which could impact the estimated aggregate pre-tax charge estimate, may further support the achievement of the overall strategic objective of the restructuring plans. From the initiation of the plans through the six months ended September 30, 2018, the Company has incurred approximately $193,000, and expects to incur approximately $11,400 of additional pre-tax charges primarily from remaining employee termination benefits and facility consolidations.

The following table provides a summary of the Company's current aggregate cost estimates by major type of expense associated with the restructuring plans noted above:

Type of expense:	Total estimated amount expected to be incurred
Termination benefits	$	39,000
Facility closure and other exit costs (1)	32,200
Contract termination costs	20,700
Accelerated depreciation charges (2)	36,200
Other (3)	76,300
	$	204,400

(1) Includes costs to transfer product lines among facilities and outplacement and employee relocation costs.

(2) Accelerated depreciation charges are recorded as part of depreciation and amortization on the consolidated statements of operations.

(3) Consists of other costs directly related to the plan, including project management, legal, regulatory costs and other transformation related costs, such as costs to amend certain contracts.

The restructuring charges recognized for the three and six months ended September 30, 2018 and 2017, by type and by segment consisted of the following:

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]

Standards Recently Implemented

Adoption of ASU 2014-09

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) that supersedes Accounting Standards Codification ("ASC") Topic 605 (“legacy GAAP”). Subsequently, the FASB issued several updates to ASU 2014-09, which are pending content or otherwise codified in ASC Topic 606 (“ASC 606”). ASU 2014-09 includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40 (“ASC 340-40”). The Company adopted ASC 606 using the modified retrospective method (“method”) effective as of April 1, 2018 (“date of initial application”). Under this method, the cumulative effect of the adoption of ASC 606 is recognized as an adjustment to retained earnings on the date of initial application (“Transition Adjustment”), and the comparative financial statements for prior periods are not adjusted and continue to be reported under legacy GAAP. The Transition Adjustment was a decrease to retained earnings of $584,900. Financial information for fiscal years 2019 and 2018 is presented under ASC 606 and under legacy GAAP, respectively. The tables below reflect adjusted fiscal year 2019 financial statement amounts as if the Company had been reporting under legacy GAAP for items that are materially different.

The adoption of ASC 606 does not impact the Company's cash flows or the underlying economics of the Company's contracts with customers. However, the pattern and timing of revenue and profit recognition, as well as financial statement presentation and disclosures, has changed.

The significant changes and the qualitative and quantitative impact of the adoption of ASC 606 are noted below:

a.Revenue from Contracts with Customers

Generally, the Company no longer uses the units-of-delivery method, and the historical use of contract blocks to define contracts for accounting purposes has been replaced by accounting contracts as identified under ASC 606. The Company's accounting contracts under ASC 606 are for the specific number of units for which orders have been received, which is typically for fewer units than what was used to define contract blocks under legacy GAAP. In most of the Company's contracts, the customer has options or requirements to purchase additional products and services that do not represent material rights since the options are at their standalone pricing.

The primary effect of the Company’s adoption of ASC 606 (outside of the Aerospace Structures segment) was to recognize revenue over time for certain of its contracts, which is a change from recognition based on shipping terms under the legacy GAAP accounting policy.

b.Capitalized Preproduction Costs

Under legacy GAAP, certain capitalized preproduction costs were deferred over the life of the contract block; in certain situations this is not permitted under ASC 606. Accordingly, capitalized preproduction costs of $865,843 (pre-tax), net of previously recognized forward loss reserves of $343,983 (pre-tax), were eliminated, resulting in a decrease to retained earnings as of April 1, 2018.

c.Contract Assets and Contract Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract assets in the amount of $565,414 were established in the Transition Adjustment.

Contract liabilities primarily represent cash received that is in excess of revenues recognized and is contingent upon the satisfaction of performance obligations. Contract liabilities in the amount of $288,287 were established in the Transition Adjustment, which reflects consideration received prior to the date of initial application that previously represented customer advances and additional forward losses due to change in block sizes. This liability will be recognized as revenue earlier if the options are not fully exercised, or immediately if the contract is terminated prior to the options being fully exercised.

d.Contract Costs

The Company’s accounting for preproduction, tooling and certain other costs has not changed since these costs generally do not fall within the scope of ASC 340-40, however certain related assets have been reclassified from inventory to property and equipment as they are costs to fulfill obligations beyond 1 year. Incurred production costs for anticipated contracts (satisfaction of performance obligations, which have commenced because the Company expects the customer to exercise options) continue to be classified as inventory.

e.Practical Expedients

The Company has adopted ASC 606 only for contracts that were not substantially completed under legacy GAAP on the date of initial application. For these contracts, the Company has reflected the aggregate effect of all modifications executed prior to the date of initial application when identifying satisfied and unsatisfied performance obligations, for determining the transaction price and for allocating the transaction price.

The following tables summarize the impacts of adopting ASC 606 on the Company’s consolidated financial statements for the three and six months ended September 30, 2018.

Adoption of ASU 2017-07

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires an employer to report the service cost component of net periodic pension benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period, with other cost components presented separately from the service cost component and outside of income from operations. ASU 2017-07 also allows only the service cost component of net periodic pension benefit cost to be eligible for capitalization when applicable. ASU 2017-07 was effective for years beginning after December 15, 2017. The Company adopted this standard on April 1, 2018, applying the presentation requirements retrospectively. We elected to apply the practical expedient, which allows us to reclassify amounts disclosed previously in the employee benefit plans note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. Provisions related to presentation of the service cost component eligibility for capitalization were applied prospectively.

The effect of the retrospective presentation change related to the net periodic benefit cost of our defined benefit pension and postretirement plans on our condensed consolidated statements of operations was as follows:

	For the Three Months Ended
	As Previously Reported September 30, 2017		Impact of Adoption of ASU 2017-07			As Adjusted September 30, 2017
Cost of sales	$	579,864	$	18,539		$	598,403
Selling, general and administrative	74,581		861			75,442
Pension settlement charge	523		(523		)	—
Non-service defined benefit income	—		(18,877		)	(18,877		)
	For the Six Months Ended
	As Previously Reported September 30, 2017		Impact of Adoption of ASU 2017-07			As Adjusted September 30, 2017
Cost of sales	$	1,207,210	$	37,000		$	1,244,210
Selling, general and administrative	153,883		1,806			155,689
Pension settlement charge	523		(523		)	—
Non-service defined benefit income	—		(38,283		)	(38,283		)

During the first quarter of the fiscal year ended March 31, 2019, the Company recorded a non-cash charge related to the adoption of ASU 2017-07 of $87,241 due to an inseparable change in estimate from a change in accounting principles. This charge is presented on the accompanying condensed consolidated statements of operations within "Cost of sales."

Adoption of ASU 2017-12

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which expands component and fair value hedging, specifies the presentation of the effects of hedging instruments, and eliminates the separate measurement and presentation of hedge ineffectiveness. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU 2017-12 as of April 1, 2018. The adoption of ASU 2017-12 did not have a material impact on the Company’s condensed consolidated financial statements.

Standards Issued Not Yet Implemented

In February 2018, the FASB issued ASU 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The guidance in ASU 2018-02 allows an entity to elect to reclassify the stranded tax effects related to the Tax Cuts and Jobs Act of 2017 (the “Act”) from accumulated other comprehensive income into retained earnings. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material effect on the Company’s condensed consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The Company makes estimates of the cost of satisfying the performance obligations in its contracts that may extend over many years. Cost estimates reflect currently available information and the impact of any changes to cost estimates, based upon the facts and circumstances, are recorded in the period in which they become known.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. The Company’s contracts with customers are typically for products and services to be provided at fixed stated prices but may also include variable consideration. Variable consideration may include, but is not limited to, unpriced contract modifications; cost sharing provisions; incentives and awards; non-warranty claims and assertions; provisions for non-conformance and rights to return; or other payments to, or receipts from, customers. The Company estimates the variable consideration using the expected value or the most likely amount based upon the facts and circumstances, available data and trends, and the history of resolving variability with specific customers.

The Company regularly commences work and incorporates customer-directed changes prior to negotiating pricing terms for engineering work, product modifications, and other statements of work. The Company's contractual terms typically provide for price negotiations after certain customer-directed changes have been accepted by the Company. Prices are estimated and related costs are deferred until they are contractually agreed upon with the customer. When a contract is modified, the Company evaluates whether additional distinct products and services have been promised and whether allocation of consideration is necessary. If not, the modification is treated as a change to the performance obligations within the existing contract, or otherwise accounted for as a new contract prospectively.

The Company allocates the consideration for a contract to the performance obligations on the basis of their relative standalone selling price. The Company estimates the likelihood of the amount of options that the customer is going to exercise when assessing the existence of performance obligations with respect to this allocation or for assessing the impact of loss contracts. The Company typically provides warranties on all of the Company's products and services. Warranties are typically not priced separately and customers cannot purchase them independently of the products or services under contract; therefore, warranties do not create performance obligations. Triumph's warranties generally provide assurance to the Company's customers that the products or services meet the specifications in the contract. In the event that there is a warranty claim because of a covered material or workmanship issue, the Company may be required to pay the customer for repairs or to perform the repair. Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These costs are accrued at the time of the sale and are recorded as cost of sales. These estimates are established using historical information on the nature, frequency, and the cost experience of warranty claims. In the case of new development products or new customers, the Company also considers other factors such as the type and nature of the new product or new customer, among others; these considerations involve the use of management judgment. Actual results could differ from those estimates and assumptions.

For the three months ended September 30, 2018, cumulative catch-up adjustments from changes in estimates, including changes in forward loss estimates, increased net sales, operating loss, net loss, and loss per share by approximately $3,459, $(10,191), $(10,191) and $(0.21), net of tax, respectively.

Revenue Recognition

A significant majority of the Company’s revenues are from long-term supply agreements with various aerospace manufacturers. The Company participates in its customers’ programs by providing design, development, manufacturing, and support services across its various segments. During the early stages of a program, this frequently involves non-recurring design and development services, including tooling. As the program matures, the Company provides recurring manufacturing of products in accordance with customer design and schedule requirements. Many contracts include clauses that provide sole supplier status to the Company for the duration of the program’s life. The Company's long-term supply agreements typically include fixed price volume-based terms and require the satisfaction of performance obligations for the duration of the program’s life.

The identification of an accounting contract with a customer and the related promises requires an assessment of each party’s rights and obligations regarding the products or services to be transferred, including an evaluation of termination clauses and presently enforceable rights and obligations. In general, these long-term supply agreements are legally governed by Master Supply Agreements (or General Terms & Agreement) under which special business provisions (or work package agreements) define specific program requirements. Purchase orders (or authorizations to proceed) are issued under these agreements to reflect presently enforceable rights and obligations for the units of products and services being purchased. The units for accounting purposes (“accounting contract”) are typically determined by the purchase orders. Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. A single program may result in multiple contracts for accounting purposes, and within the respective contracts, non-recurring work elements and recurring work elements may result in multiple performance obligations. The Company generally contracts directly with its customers and is the principal in all current contracts.

Management considers a number of factors when determining the existence of a contract and the related performance obligations that include, but are not limited to: the nature and substance of the business exchange; the contractual terms and conditions; the promised products and services; the termination provisions in the contract; the presently enforceable rights and obligations of the parties to the contract; the nature and execution of the customer’s ordering process and how the Company is authorized to perform work; whether the promised products and services are capable of being distinct and are distinct within the context of the contract; as well as how and when products and services are transferred to the customer.

Revenue is recognized when, or as, control of promised products or services transfers to a customer and is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those products or services. Revenue is recognized over time as work progresses when the Company is entitled to the reimbursement of costs plus a reasonable profit for work performed for which the Company has no alternate use or when performing work on a customer-owned asset. For these performance obligations that are satisfied over time, the Company generally recognizes revenue using an input method with revenue amounts being recognized proportionately as costs are incurred relative to the total expected costs to satisfy the performance obligation. The Company believes that costs incurred as a portion of total estimated costs is an appropriate measure of progress toward satisfaction of the performance obligation since this measure reasonably depicts the progress of the work effort.

Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer (which is generally based on shipping terms). For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Shipping and handling costs are not considered performance obligations and are included in cost of sales as incurred.

The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. A subset of the Company’s current contracts include significant financing components because the timing of the transfer of the underlying products and services under contract are at the customers’ discretion. The Company's contracts with customers generally require payment under normal commercial terms after delivery. Payment terms are typically within 30 to 120 days of delivery. The total transaction price is allocated to each of the identified performance obligations using the relative standalone selling price to reflect the amount the Company expects to be entitled for transferring the promised products and services to the customer. A majority of the Company’s agreements with customers include options for future purchases. As allowed by ASC 606, for all of its contracts the Company has elected to exclude sales and other similar taxes from the transaction price since the Company generally is not subject to collecting sales tax. As a result, the Company's collections from customers for these taxes are on a net basis.

Standalone selling price is the price at which the Company would sell a promised good or service separately to a customer. Standalone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When standalone selling prices for the Company’s products and services are generally not observable, the Company uses either the “Expected Cost plus a Margin” or "Adjusted Market Assessment" approaches to determine standalone selling price. Expected costs are typically derived from the available periodic forecast information. If a contract modification changes the overall transaction price of an existing contract, the Company allocates the new transaction price on the basis of the relative standalone selling prices of the performance obligations, and cumulative adjustments, if any, are recorded in the current period.

The Company also identifies and estimates variable consideration for contractual provisions such as unpriced contract modifications, cost sharing provisions, and other receipts or payments to customers. The timing of satisfaction of performance obligations and actual receipt of payment from a customer may differ and affects the balances of the contract assets and liabilities.

For contracts that are deemed to be loss contracts, the Company establishes forward loss reserves for total estimated costs that are in excess of total estimated consideration in the period in which they become known. The Company records forward loss reserves for all performance obligations in the aggregate for the accounting contract.

Included in net sales of Integrated Systems and Aerospace Structures is the non-cash amortization of acquired contract liabilities that were recognized as fair value adjustments through purchase accounting from various acquisitions. For the three months ended September 30, 2018 and 2017, the Company recognized $16,804 and $27,898 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations. For the six months ended September 30, 2018 and 2017, the Company recognized $34,038 and $57,371 of non-cash amortization, respectively, into net sales on the accompanying condensed consolidated statements of operations.

Concentration of Credit Risk

Concentration of Credit Risk

The Company’s trade accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from Boeing (representing commercial, military and space) represented approximately 15% and 10% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Gulfstream represented approximately 7% and 16% of total trade accounts receivable as of September 30, 2018 and March 31, 2018, respectively. Trade accounts receivable from Bombardier represented approximately 12% and 1% as of September 30, 2018 and March 31, 2018, respectively. The Company had no other concentrations of credit risk of more than 10%.

Sales to Boeing for the six months ended September 30, 2018, were $527,896, or 31% of net sales, of which $110,971, $410,133, and $6,792 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Boeing for the six months ended September 30, 2017, were $507,330, or 33% of net sales, of which $105,304, $397,817 and $4,209 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

Sales to Gulfstream for the six months ended September 30, 2018, were $174,805, or 10% of net sales, of which $1,065, $173,437, and $303 were from the Integrated Systems, Aerospace Structures and Product Support, respectively. Sales to Gulfstream for the six months ended September 30, 2017, were $198,525, or 13% of net sales, of which $654, $197,674, and $197 were from the Integrated Systems, Aerospace Structures and Product Support, respectively.

No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries.

Stock-Based Compensation

Stock-Based Compensation

The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for the three months ended September 30, 2018 and 2017, was $3,266 and $3,459, respectively. Stock-based compensation expense for the six months ended September 30, 2018 and 2017, was $5,728 and $3,418, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to employees. Upon the exercise of stock options or vesting of restricted stock, the Company first transfers treasury stock, then issues new shares.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its divestitures (see Note 3).

16.    RESTRUCTURING COSTS

During the fiscal years ended March 31, 2017 and 2016, the Company committed to restructuring plans involving certain of its businesses, as well as the consolidation of certain of its facilities. These plans are nearing completion, and as a result, the Company will have reduced its footprint by approximately 4.3 million square feet, will have reduced head count by approximately 2,500 employees and will have amended certain contracts. The Company originally estimated that it would record aggregate pre-tax charges of $195,000 to $210,000 related to these programs, which represent employee termination benefits, contract termination costs, accelerated depreciation, and facility closure and other exit costs. These charges have resulted in cash outlays and will continue to do so until the completion of the related programs. As of September 30, 2018, the Company has updated its estimate of the expected aggregate pre-tax charge to $204,400 upon completion of the restructuring and is considering whether additional programs, which could impact the estimated aggregate pre-tax charge estimate, may further support the achievement of the overall strategic objective of the restructuring plans. From the initiation of the plans through the six months ended September 30, 2018, the Company has incurred approximately $193,000, and expects to incur approximately $11,400 of additional pre-tax charges primarily from remaining employee termination benefits and facility consolidations.

The following table provides a summary of the Company's current aggregate cost estimates by major type of expense associated with the restructuring plans noted above:

Type of expense:	Total estimated amount expected to be incurred
Termination benefits	$	39,000
Facility closure and other exit costs (1)	32,200
Contract termination costs	20,700
Accelerated depreciation charges (2)	36,200
Other (3)	76,300
	$	204,400

(1) Includes costs to transfer product lines among facilities and outplacement and employee relocation costs.

(2) Accelerated depreciation charges are recorded as part of depreciation and amortization on the consolidated statements of operations.

(3) Consists of other costs directly related to the plan, including project management, legal, regulatory costs and other transformation related costs, such as costs to amend certain contracts.

The restructuring charges recognized for the three and six months ended September 30, 2018 and 2017, by type and by segment consisted of the following:
